Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro93 of human CT45-1 protein. Antibodies are purified by peptide affinity chromatography.
Background
Cancer/testis antigens (CTAs) are a family of more than 100 proteins whose normal expression is largely restricted to immune privileged germ cells of the testis, ovary, and trophoblast cells of the placenta. Although most normal somatic tissues are void of CTA expression, due to epigenetic silencing of gene expression, their expression is upregulated in a wide variety of human solid and liquid tumors (1,2). As such, CTAs have garnered much attention as attractive targets for a variety of immunotherapy-based approaches to selectively attack tumors (3).
The CT45 family is a tandem cluster of highly similar genes which share many features with other classic CT genes including Xq localization, multigene family, and identical or near-identical gene copies indicating recent gene duplications (4). The nuclear protein antigen CT45 is often highly expressed in lung cancer and ovarian cancer, and the frequency and characteristics of CT45 expression are similar to that of other CT cancer vaccine targets currently in clinical trials, including NY-ESO-1 and MAGE-A (5). Overexpression of CT45A1 in breast cancer cells was found to upregulate various oncogenic and metastatic genes, promote epithelial-mesenchymal transition, and increase cell stemness, tumorigenesis, and metastasis (6). Additionally, research studies have shown that CT45A1 silencing suppresses cell proliferation and metastasis in breast and lung cancer cells by downregulating the ERK/CREB signaling pathway (6,7). Therefore, CT45A1 and other CT45 family members are excellent targets for anticancer drug discovery and targeted tumor therapy.

Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
