Angiogenin Protein, Human

Angiogenin Protein, Human is a potent inducer of new blood vessel formation. Angiogenin may contribute to the malignant transformation of gliomas as well as to angiogenic processes.

Angiogenin (Ang) is one of the members of the pancreatic ribonuclease (RNase) superfamily that have unusual biological properties. The amino acid sequence of angiogenin revealed that it was homologous to RNase A. It shares 33% sequence identity with the bovine enzyme, including counterparts to the two histidines and one lysine that constitute the catalytic active site. It belongs to the pancreatic RNase superfamily of proteins and is specifically endocytosed by endothelial cells and transported to the nucleus, where it accumulates in the nucleolus.

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.

Approximately 14.0 kDa

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized after extensive dialysis against 20 mM PBS, 150 mM NaCl, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
