Description

SHP-2 (Phospho-Tyr542) Cell-Based ELISA Kit

The SHP-2 (Phospho-Tyr542) Cell-Based ELISA Kit is a convenient, lysate- free, high throughput and sensitive assay kit that can monitor SHP-2 phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated SHP-2 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on SHP-2 phosphorylation.

How does our SHP-2 (Phospho-Tyr542) Fluorometric Cell-Based ELISA Kit work?

Qualitative determination of SHP-2 (Phospho-Tyr542) concentration is achieved by an indirect ELISA format. In essence, SHP-2 (Phospho-Tyr542) is captured by SHP-2 (Phospho-Tyr542)-specific primary (1°) antibodies while Dye 1-conjugated and Dye 2-conjugated secondary (2°) antibodies bind the Fc region of the 1° antibody. Through this binding, the dye conjugated to the 2° antibody can emit light at a certain wavelength given proper excitation, hence allowing for a fluorometric detection method. Due to the qualitative nature of the Cell-Based ELISA, multiple normalization methods are needed:

1.	A monoclonal antibody specific for human GAPDH is included to serve as an internal positive control in normalizing the target RFU values.
2.	An antibody against the nonphosphorylated counterpart of SHP-2 (Phospho-Tyr542) is also provided for normalization purposes. The RFU values obtained for non-phosphorylated SHP-2 can be used to normalize the RFU value for phosphorylated SHP-2.

Kit Protocol

This is a summarized version of the kit protocol. Please view the technical manual of this kit for information on sample preparation, reagent preparation and plate lay out.

1.	Seed 200 µl of desired cell concentration in culture medium into each well of the 96-well plates. For suspension cells and loosely attached cells, coat the plates with 100 µl of 10 µg/ml Poly-L-Lysine (not included) to each well of a 96-well plate for 30 minutes at 37°C prior to adding cells.
2.	Incubate the cells for overnight at 37°C, 5% CO2.
3.	Treat the cells as desired.
4.	Remove the cell culture medium and rinse with 200 µl of 1x TBS, twice.
5.	Fix the cells by incubating with 100 µl of Fixing Solution for 20 minutes at room temperature. The 4% formaldehyde is used for adherent cells and 8% formaldehyde is used for suspension cells and loosely attached cells.
6.	Remove the Fixing Solution and wash the plate 3 times with 200 µl 1x Wash Buffer for 3 minutes. The plate can be stored at 4°C for a week.
7.	Add 100 µl of Quenching Buffer and incubate for 20 minutes at room temperature.
8.	Wash the plate 3 times with 1x Wash Buffer for 3 minutes each time.
9.	Dispense 200 µl of Blocking Buffer and incubate for 1 hour at room temperature.
10.	Wash 3 times with 200 µl of 1x Wash Buffer for 3 minutes each time.
11.	Add 50 µl of Primary Antibody Mixture P to corresponding wells for SHP-2 (Phospho-Tyr542) detection. Add 50 µl of Primary Antibody Mixture NP to the corresponding wells for total SHP-2 detection. Cover the plate with parafilm and incubate for 16 hours (overnight) at 4°C. If the target expression is known to be high, incubate for 2 hours at room temperature.
12.	Wash 3 times with 200 µl of 1x Wash Buffer for 3 minutes each time.

SHP-2 (Phospho-Tyr542) - Protein Information

UniProt Protein Function:	SHP-2: a SH2-containing a ubiquitously expressed tyrosine-specific protein phosphatase. It participates in signaling events downstream of receptors for growth factors, cytokines, hormones, antigens and extracellular matrices in the control of cell growth, differentiation, migration, and death. Activation of SHP-2 and its association with Gab1 is critical for sustained Erk activation downstream of several growth factor receptors and cytokines.

NCBI Summary:	The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP contains two tandem Src homology-2 domains, which function as phospho-tyrosine binding domains and mediate the interaction of this PTP with its substrates. This PTP is widely expressed in most tissues and plays a regulatory role in various cell signaling events that are important for a diversity of cell functions, such as mitogenic activation, metabolic control, transcription regulation, and cell migration. Mutations in this gene are a cause of Noonan syndrome as well as acute myeloid leukemia. Two transcript variants encoding different isoforms have been found for this gene.
