Abcam’s STAT5 A/B (pY694/699) in vitro SimpleStep ELISA™ (Enzyme-Linked Immunosorbent Assay) kit is designed for the semi-quantitative measurement of STAT5 A/B (pY694/699) protein in Human cells.
The SimpleStep ELISA™ employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB substrate is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm
Abcam’s STAT5 A/B (pY694/699) SimpleStep ELISA kit (ab176656) has been re-developed with new detector antibody. From February 18, 2016 the kit will be delivered with a new detector total STAT5 antibody. This change was necessary because of a decrease in the performance of the polyclonal STAT5 antibody that was previously used for detection in recent production lots. We have identified a new antibody to use in the SimpleStep ELISA platform that provides higher performance.

Example of a typical STAT5 A/B (pY694/699) cell lysate dilution series. Background-subtracted data values (mean +/- SD) are graphed.
A431 cells were cultured in 96-well tissue culture plates and treated (15 min) with a dose-range of EGF before cell lysis. Data from quadruplicate measurements of STAT5 A/B (pY694/699) are plotted and compared against Total STAT5 A/B levels.
Cell line analysis for Total STAT5 A/B from 100 µg/mL preparations of cell extracts. Data from triplicate measurements (mean +/- SD) are plotted and compared to 1X Cell Extraction Buffer PTR (zero).
