SEE ALSO...

Brn-3a Antibody (14A6) is a mouse monoclonal IgG2b kappa light chain antibody that detects Brn-3a protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). Anti-Brn-3a antibody (14A6) 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. Brn-3a, a member of the Brn family of transcription factors, plays a crucial role in the development of the central nervous system by regulating the expression of genes necessary for neuronal differentiation and survival. Brn-3a (14A6) monoclonal antibody recognizes a highly restricted subset of neurons, where Brn-3a is essential for proper formation of sensory neurons and retinal development. Brn-3a′s unique structure includes two functional transactivating domains, which enhance transcription stimulation, making Brn-3a vital for target gene expression during early embryonic development. Understanding Brn-3a function and localization helps elucidate mechanisms underlying neurogenesis and potential implications in neurodegenerative diseases.

Rated 1 out of 5 by from Non ha funzionato in ImmunofluorescenzaHo comprato questo free sample in data 24/11/20, provato su gangli dorsali di topo in immunofluorescenza da tessuto fresh frozen. Purtroppo il segnale dell'anticorpo è aspecifico e dà un forte background anche a diverse diluizioni anche cambiando il secondario.
