RAG1 Antibody recognizes recombination activating gene 1 protein, a nuclear enzyme required for the formation of functional immunoglobulin and T cell receptor genes. RAG1 is the catalytic component of the RAG recombinase complex, which also contains RAG2. During early B and T lymphocyte development, this complex initiates VDJ recombination by recognizing conserved recombination signal sequences located adjacent to variable, diversity and joining gene segments. RAG1 directly participates in DNA binding and cleavage, while RAG2 supports stable substrate recognition and regulates the activity of the complex. This programmed DNA rearrangement generates the diverse antigen receptor repertoire required for adaptive immunity.
The RAG1-RAG2 complex recognizes recombination signal sequences containing conserved heptamer and nonamer elements separated by either a 12-base-pair or 23-base-pair spacer. Pairing of signal sequences according to the 12/23 rule helps ensure appropriate joining of antigen receptor gene segments. RAG1 first introduces a single-strand nick at the junction between a coding segment and its recombination signal sequence. A subsequent transesterification reaction generates hairpin-sealed coding ends and blunt signal ends. These DNA intermediates are processed and joined by the nonhomologous end joining machinery, producing rearranged immunoglobulin or T cell receptor genes. A RAG1 Antibody can be used to investigate the expression and localization of this essential VDJ recombination factor.
RAG1 expression is tightly controlled during lymphocyte development to restrict DNA cleavage to appropriate developmental stages. It is induced in immature B cells in the bone marrow and developing T cells in the thymus, where antigen receptor gene rearrangement occurs. RAG1 expression is normally reduced after productive receptor assembly, although it may be reactivated during receptor editing in selected developing B cells. Because RAG-mediated cleavage intentionally produces DNA double-strand breaks, its activity must be coordinated with cell cycle control, chromatin accessibility and DNA repair. Improper targeting or repair of RAG-generated breaks can contribute to chromosomal rearrangements and genomic instability in lymphoid cells.
Pathogenic variants affecting RAG1 can impair antigen receptor formation and disrupt B and T cell development. Severe loss-of-function variants are associated with forms of severe combined immunodeficiency, whereas variants retaining partial activity can produce a broader range of immune phenotypes, including Omenn syndrome, combined immunodeficiency, immune dysregulation and autoimmunity. Experimental analysis of RAG1 is therefore relevant to research involving lymphocyte maturation, immunodeficiency, antigen receptor diversity, DNA repair and lymphoid malignancy. Researchers may use RAG1 Antibody products in western blot, immunohistochemistry, immunofluorescence or other validated applications to examine protein expression in cells and tissues. NSJ Bioreagents supplies RAG1 Antibody options for studying VDJ recombination, adaptive immune development and the molecular mechanisms that generate antigen receptor diversity.

Optimal dilution of the RAG1 antibody should be determined by the researcher.
Amino acids KHHWLYTSKYLQKFMNA from the human protein were used as the immunogen for the RAG1 antibody.
After reconstitution, the RAG1 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
