Purification and characterization of acidic fibroblast growth factor from bovine brain.
Acidic brain fibroblast growth factor has been purified a minimum of 35,000-fold to apparent homogeneity by a combination of differential salt precipitation, ion exchange chromatography, gel filtration, isoelectric focusing, and hydrophobic chromatography on a C4 reversed-phase HPLC column. Two microheterogeneous forms of the molecule are obtained with apparent molecular masses of 16,600 and 16...
متن کاملPurification and partial characterization of an acidic fibroblast growth factor from bovine pituitary.
Isoelectric focusing has allowed us to fractionate pituitary extracts into basic (pI 8-9) and acidic (pI 4-5) fibroblast growth factor. The acidic fibroblast growth factor (a) is stable upon refocusing, (b) migrates as an acidic protein in urea-containing gel electrophoresis; (c) is not cell-specific, being active with fibroblasts, adrenal, and glial cells, and (d) is a heterogeneous protein fr...
متن کاملPurification of the fibroblast growth factor activity from bovine brain.
The purification of the fibroblast growth factor (FGF) from bovine brain has led to the isolation of two peptides. FGF-1 with 128 amino acids and FGF-2 with 107 amino acids. The biological activity of these two peptides is acid- and heat-labile. As indicated by the amino acid composition of FGF-1 and -2, these two peptides are derived from a common precursor and bear no resemblance to pituitary...

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولHeterologous expression of a truncated form of human recombinant vascular endothelial growth factor-A and its biological activity in wound healing
Objective(s): Vascular endothelial growth factor (VEGF) is one of the most effective proteins in angiogenesis, mesenchymal stem cells (MSCs) differentiation and wound healing. These abilities are therapeutic potential of VEGF in diabetic retinopathy, nephropathy and other tissue damage circumstances. In this study, recombinant VEGF was produced in Escherichia coli (E. coli) system and then biol...
