Storage Conditions	The lyophilized, biotinylated antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for up to twelve months from date of receipt. The reconstituted bioin conjugate can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted conjugate, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.
Product Description	Angiogenin (Ang) is a small polypeptide that is implicated in angiogenesis (formation of new blood vessels) in tumor growth . However, angiogenin is unique among the many proteins that are involved in angiogenesis in that it is also an enzyme with an amino acid sequence 33% identical to that of bovine pancreatic ribonuclease (RNase). Moreover, although Ang has the same general catalytic properties as RNase A - it cleaves preferentially on the 3' side of pyrimidines and follows a transphosphorylation/hydrolysis mechanism - its activity differs markedly both in magnitude and in specificity.Although angiogenin contains counterparts for the key catalytic residues of bovine pancreatic RNase A, it cleaves standard RNase substrates 105 - 106 times less efficiently than does RNase A. Despite this apparent weakness, the enzymatic activity of Ang appears to be essential for biological activity: replacements of important active site residues invariably diminish ribonuclease and angiogenesis activities in parallel, and a substitution that increases enzymatic activity also enhances angiogenic potency. Angiogenin may function as a tRNA-specific ribonuclease that binds to actin on the surface of endothelial cells; once bound, angiogenin is endocytosed and translocated to the nucleus, thereby promoting the endothelial invasiveness necessary for blood vessel formation. Angiogenin induces vascularization of normal and malignant tissues, and abolishes protein synthesis by specifically hydrolyzing cellular tRNAs. Alternative splicing results in two transcript variants encoding the same protein. This gene and the gene that encodes ribonuclease, RNase A family, 4 share promoters and 5' exons. Each gene splices to a unique downstream exon that contains its complete coding region.

Manufacturer - Specificity	Goat Anti-Human Angiogenin (ANG) recognizes Human ANG. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.
RRID	AB_2828144
Formulation	This biotinylated antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 containing 50 µg of bovine serum albumin per µg of antibody with no calcium, magnesium, or preservatives present.
Immunogen	E. coli-Derived Reecombinant Human ANG
