General description
Recombinant, human angiogenin expressed in E. coli. Exhibits angiogenic and ribonucleolytic activities. Enhances the ability of endothelial cells to digest extracellular matrix components and degrade basement membrane. Has been shown to stimulate capillary and umbilical vein endothelial cells to produce DAG and secrete prostacyclin by phospholipase activation. Biological activity: 1.0 µg protein produces an absorbance change at 260 nm of approximately 2.0 - 3.0 as measured by yeast tRNA ribonucleolytic activity.
Biochem/physiol Actions
≥1.0 µg protein produces an absorbance change at 260 nm of ~2.0-3.0 as measured based upon its ribonucleolytic activity toward Yeast tRNA.
Warning
Toxicity: Standard Handling (A)
Physical form
Lyophilized from sterile-filtered PBS containing 50 µg BSA/µg Angiogenin.
Reconstitution
Following reconstitution, aliquot and freeze (-70°C). Stock solutions are stable for up to months at -70°C. Avoid freeze/thaw cycles of solutions.
Reconstitute to a concentration ≥1 µg/ml with sterile PBS containing ≥0.1% HSA or BSA.

ImmunoRNases represent a highly attractive alternative to conventional immunotoxins for cancer therapy. Quantitative production of immunoRNases in appropriate expression systems, however, remains a major challenge for further clinical development of these novel compounds. Here we describe a method for high-level
