The PDGFRalpha (Phospho-Tyr713) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect PDGFRalpha protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated PDGFRalpha in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on PDGFRalpha phosphorylation.

Qualitative determination of PDGFRalpha (Phospho-Tyr713) concentration is achieved by an indirect ELISA format. In essence, PDGFRalpha (Phospho-Tyr713) is captured by PDGFRalpha (Phospho-Tyr713)-specific primary antibodies while the HRP-conjugated secondary antibodies bind the Fc region of the primary antibody. Through this binding, the HRP enzyme conjugated to the secondary antibody can catalyze a colorimetric reaction upon substrate addition. 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 absorbance values.
2. Following the colorimetric measurement of HRP activity via substrate addition, the Crystal Violet whole-cell staining method may be used to determine cell density. After staining, the results can be analysed by normalizing the absorbance values to cell amounts, by which the plating difference can be adjusted.
Database Information:Gene ID: 5175, UniProt ID: P16234, OMIM: 173445, Unigene: Hs.514412/Hs.709189
Gene Symbol:PDGFRA
Sub Type:Phospho
UniProt Protein Function:PDGFRA: a receptor tyrosine kinase of the PDGFR family that binds members of the platelet-derived growth factor family. The identity of the growth factor bound determines whether the functional receptor is a homodimer or a heterodimer, composed of both PDGFR-alpha and -beta. Ligand binding induces receptor dimerization and autophosphorylation. Particularly important for kidney development since mice heterozygous for the receptor exhibit defective kidney phenotypes. Chromosomal rearrangments activate PDGFRalpha by fusion to BCR, causing atypical chronic myelogenous leukemia (CML), and to FIP1L1, causing idiopathic hypereosinophilic syndrome. Activating point mutations cause a minority of gastrointestinal stromal tumors (GIST). Promoter polymorphisms linked to neural tube defects including spina bifida, verified by mouse mutant model. Inhibitors: Gleevec, Sutent. OMIM: Two alternatively-spliced isoforms have been described.

Disease: Gastrointestinal Stromal Tumor; Hypereosinophilic Syndrome, Idiopathic

NCBI Summary:This gene encodes a cell surface tyrosine kinase receptor for members of the platelet-derived growth factor family. These growth factors are mitogens for cells of mesenchymal origin. The identity of the growth factor bound to a receptor monomer determines whether the functional receptor is a homodimer or a heterodimer, composed of both platelet-derived growth factor receptor alpha and beta polypeptides. Studies suggest that this gene plays a role in organ development, wound healing, and tumor progression. Mutations in this gene have been associated with idiopathic hypereosinophilic syndrome, somatic and familial gastrointestinal stromal tumors, and a variety of other cancers.
