Human Phospho-Src (Y419) DuoSet IC ELISA Summary

Assay Type

Solid Phase Sandwich ELISA

Format

96-well strip plate

Assay Length

4 hours 40 minutes (after plate preparation)

Sample Volume Required

Cell lysates (100 µL)

Assay Range

3.9 - 250 pg/mL

Sufficient Materials

Kits available for two, five, or fifteen 96-well plates*

Specificity

Please see the product datasheet

* Provided that the recommended microplates, buffers, diluents, substrates and solutions are used, and the assay is run as summarized in the Assay Procedure provided.

This DuoSet IC ELISA contains the basic components required for the development of sandwich ELISAs to measure phosphorylated human Src (Y419) in cell lysates. An immobilized capture antibody specific for Src binds both phosphorylated and unphosphorylated Src. After washing away unbound material, a biotinylated detection antibody is used to detect only phosphorylated receptor, utilizing a standard HRP format.

The Human Phospho-Src (Y419) DuoSet® IC ELISA specifically recognizes human Src phosphorylated at Y419 as determined by peptide competition. A lysate prepared from MDA-MB-468 human breast cancer cells treated with 50 mM sodium pervanadate for 20 minutes was analyzed with this ELISA. The Human Phospho-Src (Y419) Detection Antibody was either untreated (no peptide) or preincubated with a phospho-peptide containing the phospho-Src Y419 phosphorylation site, a phospho-peptide containing the Ret Y905 phosphorylation site, a phospho-peptide containing the Tie-2 Y1100 phosphorylation site, or a phospho-peptide containing the PP2A Y307 phosphorylation site. Peptides were used at 40 ng/mL. Only the phospho-peptide containing the Src Y419 phosphorylation site blocked the signal, indicating that the ELISA is specific for human Src phosphorylation.

Amounts of human phosphorylated Src, as quantified by the Human Phospho-Src (Y419) DuoSet® IC ELISA, are consistent with the relative amounts of phosphorylated Src determined by qualitative Western Blot analysis. Quantification of phosphorylated Scr (Y419) in pervabadate-treated human MDA-MB-468 cells. Lysates prepared from MDA-MB-468 human breast cancer cells treated with 50 mM sodium pervanadate for the indicated times were quantified with this DuoSet® IC ELISA. The same lysates were also immunoblotted (inset) with either Human Phospho-Src (Y419) Polyclonal Antibody (Catalog # AF2685) or Human/Mouse/Rat Src Polyclonal Antibody (Catalog # AF3389). The DuoSet® IC ELISA results are consistent with the relative amounts of phosphorylated Src family members detected by Western Blot. The immunoblot with anti-Src antibody indicated that total levels of human Src remained constant during incubation with sodium pervanadate.

Background: Src

Src and other Src family protein tyrosine kinases are proto-oncogenes that play key roles in regulating cell growth and differentiation. Src family activity is regulated by tyrosine phosphorylation at two sites with opposing effects. Phosphorylation at Y419 of human Src up-regulates kinase activity, while phosphorylation at Y530 inactivates Src.
