Description

Human TNFRSF21 (Tumor necrosis factor receptor superfamily member 21) ELISA Kit

The Human TNFRSF21 (Tumor Necrosis Factor Receptor Superfamily Member 21) ELISA Kit is specifically designed for the accurate measurement of TNFRSF21 levels in human samples such as serum, plasma, and cell culture supernatants. With its high sensitivity and specificity, this kit offers reliable and reproducible results, making it an excellent choice for various research applications.TNFRSF21 is a critical receptor protein that plays a key role in regulating immune responses and cell death.

It is involved in various physiological processes and is implicated in conditions such as inflammation, autoimmune diseases, and cancer. Therefore, this ELISA kit serves as a valuable tool for studying TNFRSF21's role in these diseases and developing potential therapeutic interventions.Overall, the Human TNFRSF21 ELISA Kit from Assay Genie provides researchers with a powerful platform to explore the functions and implications of TNFRSF21 in different biological contexts.

Note:For Research Use Only
Recovery: Matrices listed below were spiked with certain level of TNFRSF21 and the recovery rates were calculated by comparing the measured value to the expected amount of TNFRSF21 in samples.
MatrixRecovery range(%)Average(%)
serum(n=5)91-9795
EDTA plasma(n=5)92-10398
heparin plasma(n=5)91-10096
Linearity: The linearity of the kit was assayed by testing samples spiked with appropriate concentration of TNFRSF21 and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

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 TypeProtocol
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.

PlasmaCollect 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 FluidCollect 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 supernatantCollect 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 lysatesSolubilize 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 homogenatesThe 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 lysatesRinse 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 MilkCollect 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.
