The BHLH79 antibody targets a protein known as BHLH79, which belongs to the basic helix-loop-helix (bHLH) family of transcription factors . These proteins are characterized by a bHLH domain that facilitates DNA binding and protein dimerization, playing crucial roles in various biological processes, including cell differentiation, development, and responses to environmental stimuli .
BHLH79 proteins, as members of the bHLH family, typically function as transcription factors that regulate gene expression . They often form dimers with other bHLH proteins to bind to specific DNA sequences, thereby influencing the transcription of target genes.
BHLH79 antibodies are valuable tools for:
Studying Protein Expression: They can be used to detect the presence and levels of BHLH79 protein in different tissues or cell types .
Analyzing Subcellular Localization: These antibodies can help determine where BHLH79 protein is located within cells .
Investigating Protein Function: By blocking or detecting BHLH79, researchers can elucidate its role in various biological processes .
Cold Stress Response: In Brassica campestris, CabHLH79 enhances cold tolerance by upregulating the expression of genes related to reactive oxygen species (ROS) and other cold stress tolerance mechanisms .
Immune Response to Tuberculosis: Research has identified human antibodies against Mycobacterium tuberculosis (MTB) antigens, revealing insights into the human B-cell response to MTB . These antibodies, including IgA isotypes, can block MTB uptake by lung epithelial cells .
Cancer Immunotherapy: Identification of immunogenic epitopes that bind to the major histocompatibility complex (MHC) is critical for personalized cancer vaccines and cell therapies .
Western Blotting: Used to confirm the specificity of antibodies by identifying target proteins based on their molecular weight .
ELISA (Enzyme-Linked Immunosorbent Assay): Employed to detect and quantify the interaction between antibodies and antigens .
Flow Cytometry: Used to assess antibody binding to cells, helping to identify and sort cell populations based on BHLH79 expression .
Immunofluorescence Microscopy: Helps visualize the localization of BHLH79 protein within cells and tissues .
