Sub Unit:Monomer (PubMed:9003371, PubMed:19948503). Oligomer. Heterodimer. Homodimer (PubMed:19948503). Cis-dimer/oligomer (via Ig-like C2-type and/or via cytoplasmic domains); induced by trans-homophilic cell adhesion through an allosteric mechanism transmitted by the Ig-like V-type domain, and is regulated by intracellular calcium and calmodulin (PubMed:19948503, PubMed:2373740, PubMed:8831574, PubMed:9003371). Interacts (via cytoplasmic domain) with calmodulin in a calcium dependent manner; reduces homophilic cell adhesion through dissociation of dimer (PubMed:8576129). Isoform 1 interacts (via cytoplasmic domain) with PTPN11 (preferentially) and PTPN6; cis-homodimer form is preferred; this interaction is decreased by formation of isoform 1 / isoform 2 cis-heterodimers and is dependent on the monomer/dimer equilibrium; this interaction is phosphorylation-dependent (PubMed:19948503). Isoform 1 interacts with LYN (By similarity). Isoform 1 interacts (via cytoplasmic domain) with SRC (via SH2 domain); this interaction is regulated by trans-homophilic cell adhesion (PubMed:19948503). Isoform 1 interacts (via cytoplasmic domain) with LCK; mediates phosphorylation at Tyr-488 and Tyr-513 resulting in PTPN6 association. Isoform 1 interacts with PTPN6; this interaction is phosphorylation-dependent and causes a profound decrease in TCR stimulation-induced CD247 and ZAP70 phosphorylation. Isoform 1 interacts with TCR/CD3 complex through TCR beta chain and CD3E; colocalizes at the cell surface and upon stimulation of the TCR/CD3 complex recuits PTPN6 in the TCR/CD3 complex, resulting in dephosphorylation of CD247 and ZAP70 (By similarity). Isoform 1 interacts (via cytoplasmic domain) with SHC1 (via SH2 domain); SHC1 mediates interaction with INSR or EGFR in a Ser-503 phosphorylation-dependent manner (PubMed:11694516). Isoform 1 interacts with EGFR; the interaction is indirect (PubMed:15467833). Isoform 1 interacts with CSF3R; down-regulates the CSF3R-STAT3 pathway through recruitment of PTPN6 that dephosphorylates CSF3R. Isoform 1 (phosphorylated form) interacts with TLR4 and SYK; recruits PTPN6 that dephosphorylates SYK, reducing the production of reactive oxygen species (ROS) and lysosome disruption, leading to a reduction of the inflammasome activity (By similarity). Isoform 1 interacts with FLNA; inhibits cell migration and cell scattering by interfering with the interaction of FLNA with RALA (PubMed:16291724). Isoform 1 interacts (via cytoplasmic domain) with PXN; the interaction is phosphotyrosyl-dependent. Isoform 1 interacts with KLRK1; recruits PTPN6 that dephosphorylates VAV1. Isoform 1 interacts with CEACAM8 (By similarity). Isoform 1 interacts with FASN; this interaction is insulin and phosphorylation-dependent; reduces fatty-acid synthase activity (PubMed:16054098). Interacts (via Ig-like V-type) with HAVCR2 (via Ig-like V-type); facilitates the maturation and cell surface expression of HAVCR2 thereby regulating T-cell tolerance induction. Isoform 2 interacts (via the cytoplasmic domain) with ANXA2; this interaction is regulated by phosphorylation and appears in the AIIt complex. Interacts (via Lewis X moieties) with CD209 (via C-type lectin domain); this interaction is regulated by the glycosylation pattern of CEACAM1 on cell types and regulates contact between dendritic cells and neutrophils.

*Note: The below protocol is a sample protocol. Protocols are specific to each batch/lot. For the correct instructions please follow the protocol included in your kit.

Allow all reagents to reach room temperature (Please do not dissolve the reagents at 37°C directly). All the reagents should be mixed thoroughly by gently swirling before pipetting. Avoid foaming. Keep appropriate numbers of strips for 1 experiment and remove extra strips from microtiter plate. Removed strips should be resealed and stored at -20°C until the kits expiry date. Prepare all reagents, working standards and samples as directed in the previous sections. Please predict the concentration before assaying. If values for these are not within the range of the standard curve, users must determine the optimal sample dilutions for their experiments. We recommend running all samples in duplicate.

Step
1. Add Sample: Add 100µL of Standard, Blank, or Sample per well. The blank well is added with Sample diluent. Solutions are added to the bottom of micro ELISA plate well, avoid inside wall touching and foaming as possible. Mix it gently. Cover the plate with sealer we provided. Incubate for 120 minutes at 37°C.
2. Remove the liquid from each well, don't wash. Add 100µL of Detection Reagent A working solution to each well. Cover with the Plate sealer. Gently tap the plate to ensure thorough mixing. Incubate for 1 hour at 37°C. Note: if Detection Reagent A appears cloudy warm to room temperature until solution is uniform.
3. Aspirate each well and wash, repeating the process three times. Wash by filling each well with Wash Buffer (approximately 400µL) (a squirt bottle, multi-channel pipette,manifold dispenser or automated washer are needed). Complete removal of liquid at each step is essential. After the last wash, completely remove remaining Wash Buffer by aspirating or decanting. Invert the plate and pat it against thick clean absorbent paper.
4. Add 100µL of Detection Reagent B working solution to each well. Cover with the Plate sealer. Incubate for 60 minutes at 37°C.
5. Repeat the wash process for five times as conducted in step 3.
6. Add 90µL of Substrate Solution to each well. Cover with a new Plate sealer and incubate for 10-20 minutes at 37°C. Protect the plate from light. The reaction time can be shortened or extended according to the actual color change, but this should not exceed more than 30 minutes. When apparent gradient appears in standard wells, user should terminatethe reaction.
7. Add 50µL of Stop Solution to each well. If color change does not appear uniform, gently tap the plate to ensure thorough mixing.
8. Determine the optical density (OD value) of each well at once, using a micro-plate reader set to 450 nm. User should open the micro-plate reader in advance, preheat the instrument, and set the testing parameters.
9. After experiment, store all reagents according to the specified storage temperature respectively until their expiry.

When carrying out an ELISA assay it is important to prepare your samples in order to achieve the best possible results. Below we have a list of procedures for the preparation of samples for different sample types.

Sample Type Protocol
Serum If using serum separator tubes, allow samples to clot for 30 minutes at room temperature. Centrifuge for 10 minutes at 1,000x g. Collect the serum fraction and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles. If serum separator tubes are not being used, allow samples to clot overnight at 2-8°C. Centrifuge for 10 minutes at 1,000x g. Remove serum and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles.
Plasma Collect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples at 4°C for 15 mins at 1000 × g within 30 mins of collection. Collect the plasma fraction and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles. Note: Over haemolysed samples are not suitable for use with this kit.
Urine & Cerebrospinal Fluid Collect the urine (mid-stream) in a sterile container, centrifuge for 20 mins at 2000-3000 rpm. Remove supernatant and assay immediately. If any precipitation is detected, repeat the centrifugation step. A similar protocol can be used for cerebrospinal fluid.
Cell culture supernatant Collect the cell culture media by pipette, followed by centrifugation at 4°C for 20 mins at 1500 rpm. Collect the clear supernatant and assay immediately.
Cell lysates Solubilize cells in lysis buffer and allow to sit on ice for 30 minutes. Centrifuge tubes at 14,000 x g for 5 minutes to remove insoluble material. Aliquot the supernatant into a new tube and discard the remaining whole cell extract. Quantify total protein concentration using a total protein assay. Assay immediately or aliquot and store at ≤ -20 °C.
Tissue homogenates The preparation of tissue homogenates will vary depending upon tissue type. Rinse tissue with 1X PBS to remove excess blood & homogenize in 20ml of 1X PBS (including protease inhibitors) and store overnight at ≤ -20°C. Two freeze-thaw cycles are required to break the cell membranes. To further disrupt the cell membranes you can sonicate the samples. Centrifuge homogenates for 5 mins at 5000xg. Remove the supernatant and assay immediately or aliquot and store at -20°C or -80°C.
Tissue lysates Rinse tissue with PBS, cut into 1-2 mm pieces, and homogenize with a tissue homogenizer in PBS. Add an equal volume of RIPA buffer containing protease inhibitors and lyse tissues at room temperature for 30 minutes with gentle agitation. Centrifuge to remove debris. Quantify total protein concentration using a total protein assay. Assay immediately or aliquot and store at ≤ -20 °C.
Breast Milk Collect milk samples and centrifuge at 10,000 x g for 60 min at 4°C. Aliquot the supernatant and assay. For long term use, store samples at -80°C. Minimize freeze/thaw cycles.
