Refreezing should be performed on dry ice or in a dry ice/alcohol bath.

Tech Info / Data

  1. 11619 Purity Confirmation on SDS-PAGE

Recombinant Human Growth Hormone (HGH), expressed in engineered human cells, is a member of the somatotropin/prolactin family of hormones. HGH is produced from the pituitary gland and is required for normal human growth and development. HGH modifies a variety of physiological functions by stimulating the expression of insulin-like growth factor I and increases calcium retention and bone mineralization. HGH increases muscle mass, promotes lipolysis and reduces liver uptake of glucose.


Western Blot

21900-1 Western Blot for Anti-Human ISG15

Control (C) and Treated (T) 40 μg lysate samples from A549, Ovcar and HeLa cells were run alongside 50 ng recombinant ISG15 and 100 μg ubiquitin on a 12% SDS-PAGE gel under reducing conditions. Cells were either untreated (C) or treated (T) with 1000 U/ml of Human IFN beta 1a (PBL Cat. No. 11410-2) and lysed with 50 mM Tris-HCl pH8, 200 mM NaCl, 10% Glycerol, 0.5% NP-40, 0.1 mM EDTA with protease inhibitors on ice for one hour and then centrifuged at 4°C to obtain supernatants. No cross-reactivity was observed with ubiquitin at tested concentrations up to 100 μg. The antibody was additionally tested on Daudi and U937 cell lysates (data not shown).
