Isolation and characterization of proteoglycans from human follicular fluid.
Two proteoglycans differing in size and composition were isolated from human follicular fluid. The larger one of high density had a molecular mass of 3.0x10(6) Da, as determined by laser light-scattering, and was substituted with 15-20 chondroitin sulphate (CS) chains (Mr 60000-65000). Half of the CS disaccharides were 6-sulphated, whereas the remaining ones were non-sulphated. Digestion of the...
متن کاملIsolation and characterization of proteoglycans from porcine ovarian follicular fluid.
Monomer proteoglycan was isolated from porcine ovarian follicular fluid by isopycnic CsCl centrifugation in the presence of 4 M guanidine HCl and protease inhibitors. The elution profile of the D1 preparation on Sepharose 2B was similar to that of monomer proteoglycan from bovine nasal cartilage, indicating a similar molecular size. Follicular fluid proteoglycans consist of about 20% protein, 5...
متن کاملOptimization of The Cell Aggregates Method for Isolation and Purification of Human Granulosa Cells from Follicular Fluid
Objective Aspirated ovarian follicular fluids (FF) contain luteal granulosa cells (LGC) and other contaminating cell types. Several strategies such as the antibody binding methods, the flask method, the cell strainer, and the positive selection of granulosa aggregates after density gradient centrifugation, were tested as LGCs purification methods. Each of these strategies has its own advantages...
متن کاملGonadotropin-releasing peptide from human follicular fluid: isolation, characterization, and chemical synthesis.
A gonadotropin-releasing peptide has been isolated from human follicular fluid. Its amino acid composition and sequence are completely different from the hypothalamic lutropin-releasing hormone. It is designated human follicular gonadotropin-releasing peptide and abbreviated as hF-GRP. The primary structure of this peptide (H-Thr-Asp-Thr-Ser-His-His-Asp-Gln-Asp-His-Pro-Thr-Phe-Asn-OH) has been ...
متن کاملIsolation and characterization of dermatan sulphate proteoglycans from bovine sclera.
1. Proteoglycans were extracted from sclera with 4 M-guanidine hydrochloride in the presence of proteinase inhibitors and purified by ion-exchange chromatography and density-gradient centrifugation. 2. The entire proteoglycan pool was characterized by compositional analyses and by specific chemical (periodate oxidation) and enzymic (chondroitinases) degradations. The glycan moieties of the mole...
