The RBG-1 antibody (ab108318) is a rabbit monoclonal antibody developed using patented technology. It targets the BRG1 protein (SMARCA4), which has a molecular weight of ~185 kDa. Validated for use in Western blot (WB), immunohistochemistry (IHC), immunofluorescence (IF), and flow cytometry, this antibody is compatible with human, mouse, and rat samples .
High specificity: Validated using SMARCA4 knockout cell lines, with no cross-reactivity observed in knockout controls .
Batch consistency: Produced in recombinant format for reliability across experiments .
Broad application: Effective in multiple techniques, including co-staining with tubulin markers .
The antibody detects BRG1 at the expected molecular weight (185 kDa) in human, mouse, and rat lysates. Knockout validation confirms specificity:
Sample Type | Observed Band (kDa) | Specificity Confirmed? |
---|---|---|
Wild-type HAP1 cells | 185 | Yes |
BRG1 knockout HAP1 | No band | Yes |
Mouse RAW264.7 cells | 185 | Yes |

Optimized protocols for formalin-fixed paraffin-embedded tissues include:
Antigen retrieval: Tris-EDTA buffer (pH 9.0).
Dilution: 1:500 (0.23 µg/ml).
Chromatin remodeling: BRG1 regulates gene expression by altering chromatin structure, impacting cancer progression and stem cell differentiation .
Disease models: Used to investigate BRG1's role in malignancies such as lung adenocarcinoma and glioblastoma .
Co-staining: Compatible with markers like α-tubulin (Alexa Fluor® 594) .
Sensitivity: Detects BRG1 at low concentrations, critical for rare cell populations .
