Soluble collagen in human serum.
Soluble collagen-like components in whole human serum and in serum fractions obtained after filtration on Sephadex G-zoo or after sucrose density gradient centrifugation were analyzed by micro-immunodiffusion and by immunoelectrophoresis. Antiserum to human skin collagen served as the reagent for the detection of the antigen. The collagen-like components were shown to exist in at least z, and p...
متن کاملSoluble stem cell factor in human serum.
Stem cell factor (SCF) is a recently described factor active in the early stages of hematopoiesis. It can exist in membrane-bound form and in proteolytically released soluble form. The levels and nature of SCF in human serum are described. As determined by an enzyme-linked immunosorbent assay performed for 257 samples, SCF level in serum averaged 3.3 +/- 1.1 ng/mL. The serum SCF was partially p...
متن کاملSoluble kit receptor in human serum.
c-kit encodes the transmembrane receptor tyrosine kinase (Kit) for the recently described ligand stem cell factor (SCF). We have developed an enzyme-linked immunosorbent assay for measuring soluble human Kit and we have used the assay to show high levels of soluble Kit in human serum. The distribution of soluble Kit levels was investigated among 112 normal human serum donors. The mean serum lev...
متن کاملType IV collagen-degrading enzyme activity in human serum.
Type IV collagen-degrading enzyme activity was detected in human serum. Serum was preincubated with 4-aminophenylmercuric acetate and trypsin to activate the enzyme prior to assay. Type IV collagen, purified from human placentas and radiolabeled with [1-14C] acetic anhydride, was used as the substrate. The enzyme activity was measured at pH 7.5 and inhibited by treatment with ethylenediaminetet...
متن کاملSoluble IL-15/IL-15Rα complexes in human serum.
In this issue of Blood, Bergamaschi and colleagues demonstrate that effectively all circulating IL-15 found in the serum of humans and mice is associated with the soluble IL-15Rα.(1)
