The primary structure of an elephant neurophysin, homologous to vasopressin-associated neurophysins, is reported. The protein contains a Tyr for Asn substitution at position 75, a position in direct contact with residues 77 and 78 of the monomer-mono

Adrenocorticotropin and beta-lipotropin have been isolated and purified from elephant pituitary glands. The primary structures of these two hormones were determined by amino acid and sequence analyses of enzymatically cleaved peptides from the hormon

Growth hormone has been purified to homogeneity from elephant pituitary glands. It has 191 amino acids with two disulfide bridges and a single tryptophan residue. The somatotropin activity is only 15% when compared with the bovine hormone in the radi

Enhanced chemiluminescence (CL) induced by HO* was detected using the primary enhancers luminol (Lum), isoluminol (ILum) and lucigenin (Luc), in the absence of HCO3-, at pH 9.5, 10.0 and 10.5 but not between pH 4.0 and 9.0. This was confirmed using n

Oxyradicals are involved in multiple mutational events and can contribute to the conversion of healthy cells to cancer cells. Glutathione (GSH) and the GSH-replenishing enzymes keep the antioxidant status of normal cells at a level where they can ave

The compromised optima for high intensity chemiluminescence (CL), using superoxide generators, were all above pH 9.0 for the CL probes luminol and lucigenin. With luminol the optima were at pH 9.0 and 9.4 for the generators KO2 and hypoxanthine/xanth

Alterations in cellular calcium homeostasis are a critical factor in the pathogenesis of hepatic ischemic damage and may mediate oxygen free radical injury during the reperfusion period. We investigated the effect of the calcium channel blocker verap

Hepatoproliferin (HPF) was purified from regenerating rat livers as an oligomeric entity (big-HPF) from which the monomeric form (small-HPF) could be obtained using disaggregating conditions. By using a solid-phase ion-exchange method, small-HPF was

Hepatoproliferin (HPF), a liver regeneration factor, was isolated initially as an aggregated molecule (big-HPF) and was purified into two homogeneous, bioactive species of 14 kDa and 18.5 kDa. These two big-HPFs were disaggregated to completion into
