Gfi-1B Antibody (B-7) is a mouse monoclonal IgG2b kappa light chain antibody that detects Gfi-1B protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). anti-Gfi-1B antibody (B-7) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. Gfi-1B protein plays a crucial role in hematopoiesis and immune regulation, primarily functioning as a transcriptional repressor. Gfi-1B is predominantly expressed in the bone marrow and spleen, where Gfi-1B regulates the expression of genes involved in cell cycle control and immune responses. Notably, Gfi-1B directly represses the p21 promoter, which is essential for cell cycle progression, thereby influencing the proliferation and differentiation of hematopoietic cells. Gfi-1B′s ability to modulate the expression of suppressor of cytokine signaling (SOCS) genes further underscores its importance in maintaining immune homeostasis. The genes encoding human Gfi-1 and Gfi-1B are located on chromosomes 1p22 and 9q34.13, respectively, highlighting their evolutionary conservation and significance across species.

When should the TransCruz reagent sc-28356 X be used instead of the standard form sc-28356?

Asked by: jenniferc
Thank you for your question. We recommend using the TransCruz reagent form when performing ChIP or GelShift assays. This form can also be used in other applications such as Western Blot or IHC, but the dilution should be adjusted by a factor of 10 to account for the higher original concentration.
