  • Product overview

    GATA3 in vitro SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of GATA3 protein in humancell extracts.

    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.

    GATA3 is part of the GATA family of transcription factors. Trans-acting T-cell-specific transcription factor, or GATA3, is a zinc-binding transcriptional factor encoded by the GATA3 gene. GATA3 belongs to a group of transcription factors which are characterized by their ability to bind the DNA sequence “GATA”. The main function of GATA3 is to act as a main transcriptional factor for the differentiation of T helper 2 (Th2) cells. GATA3 also induces the differentiation of Th0 cells towards the Th2 subtype while suppressing differentiation to Th1 cells. GATA3 promotes the secretion of IL-4, IL-5, and IL-13 from Th2 cells.

Our Abpromise guarantee covers the use of ab230939 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Sandwich ELISA Use at an assay dependent concentration.


  • SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.


  • The concentrations of GATA3 were measured in duplicates, interpolated from the GATA3 standard curves and corrected for sample dilution. Undiluted samples are as follows: T47D cell extract 50 µg/mL and MCF7 cell extract 187.5 µg/mL. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean GATA3 concentration in the undiluted samples was determined to be 1,621 µg/mL in T47D cell extract and 3,807 µg/mL in MCF7 cell extract.

  • The GATA3 standard curve was prepared as described in Section 10. Raw data values are shown in the table. Background-subtracted data values (mean +/- SD) are graphed.
