AHP1209B is specific for the soluble form of human CD254, otherwise known as sRANKL, a 20kDa glycoprotein and member of the Tumour Necrosis Factor (TNF) superfamily, generated by proteolytic processing of the full-length CD254 membrane protein.
CD254 is highly expressed by T lymphocytes and osteoblastic cells and plays a key role in the differentiation and activation of osteoclast precursors, acting as a ligand for both receptor activator of NF-KBeta (RANK) and the decoy receptor osteoprotegerin (OPG), which act as antagonists. Binding of CD254 to RANK is essential for the activation of osteoclastogenesis, stimulated by factors such as TNF-alpha, IL-1beta, IL-6 and IL-17, whereas binding to OPG neutralizes CD254, thereby inhibiting osteoclastogenesis.
Studies have shown that CD254 augments the dendritic cell (DC) stimulation of naïve T cell proliferation and may be involved in the regulation of DC-T cell interactions. Studies have also revealed a link between CD254 and apoptosis, through activation of the antiapoptotic kinase AKT/PKB and the mTOR/S6K signalling pathway.

After reconstitution store at -20oC.
Storage in frost-free freezers is not recommended. This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.
Shelf Life
12 months from date of reconstitution.
Antiserum Preparation
Antisera to human CD254 were raised by repeated immunisations of rabbits with highly purified antigen. Purified IgG prepared by affinity chromatography.
