Abcam’s CREB1 in vitro SimpleStep ELISA™ (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of CREB1 protein in Human and mouse 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.

Example of a typical CREB1 cell lysate dilution series. Background-subtracted data values (mean +/- SD) are graphed.
Linearity of dilution in representative sample matrices. Cellular lysates were prepared at 3 concentrations in common media containing 1X Cell Extraction Buffer PTR. Data from duplicate measurements of CREB1 (Total) are normalized and plotted.
Inhibition of CREB1 (pS133) phosphorylation in MCF-7 cells in response to AG1486 treatment. HeLa cells were cultured in 96-well tissue culture plates and treated (60 min) with a dose-range of AG1486. Cells were then stimulated (10 min) with 100 ng/mL EGF and lysed. Data from quadruplicate measurements of CREB1 (pS133) are plotted and compared against total CREB1 protein levels. Comparative CREB1 (pS133) and CREB1 (Total) data also shown by Western Blot.
Cell line analysis for Total CREB1 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).
