Recombinant monoclonal antibody to BRAF V600E protein. Manufactured using AbAb’s Recombinant Platform with variable regions (i.e. specificity) from the hybridoma 600E-7.
UniProt Accession Number of Target Protein: P15056
Alternative Name(s) of Target: RAFB1; BRAF1; p94; BRAF V600E kinase; Serine/threonine-protein kinase B-raf; Proto-oncogene B-Raf; v-Raf murine sarcoma viral oncogene homolog B1
Immunogen: The original antibody was generated by immunizing mice with double repeat recombinant BRAF V600E protein 'GDFGLATEKSRW' and BRAF V600 protein 'GDFGLATVKSRW' in equal amount of complete Freund’s adjuvant.
Specificity: This antibody is specific for the V600E mutation of the BRAF protein kinase. BRAF V600E mutation can promote the methylation of the thyrotropin receptor (TSHR) gene promoter, resulting in silencing of TSHR or a significant decrease in expression, and feedback increase of thyrotropin (TSH), which promotes the growth of tumor cells. BRAF V600E gene mutation and telomerase reverse transcriptase (TERT) promoter mutation also play an important role in the occurrence of papillary thyroid carcinoma (PTC).
Application Notes: This antibody can be used for the detection of the BRAF V600E mutation. This antibody is useful in the diagnosis and targeted therapy for papillary thyroid carcinoma. The binding characterization of this antibody for BRAF V660E mutation was done using ELISA. The IgG1 version of the antibody binds the BRAF V600E mutation with a dissociation constant of 0.04 nM and IC50 of the IgG1 antibody against A375 cells was 42nM. This antibody was used in the generation of immunomagnetic beads for the detection of BRAF V600E mutation (CN111285935).

Immunofluorescence staining of with anti-BRAF V600E protein (Ab03009) 600E-7 Immunofluorescence analysis of permeabilized with 0.15% Triton stained with the chimeric rabbit IgG version of 600E-7 (Ab03009-23.0) (1:1000 dilution) for 1h followed by Alexa Fluor® 488 secondary antibody (1:1500 dilution), showing nuclear staining. The nuclear stain is DAPI (blue). Panels show from left-right, top-bottom Ab03009-23.0, DAPI, merged channels and an isotype control. The isotype control was anti-fluorescein antibody (Ab00102-23.0) followed by staining with Alexa Fluor® 488 secondary antibody.
