The culture medium in which prehatching embryos of the frog, Rana pirica, were cultured (hatching medium) solubilized the vitelline coat (VC) of unfertilized eggs and contained molecules reactive to antibodies (anti-UVS.2) against the Xenopus hatching enzyme (HE). The hydrolyzing activity

Chemical catalysis, an effector mechanism utilized by fully assembled antibodies, can also be mediated by the isolated antibody subunits. Because trace amounts of free light chains (L chains) are present in IgG preparations, a detailed study was undertaken to identify

Kallikrein in human urine was measured using a fluorogenic peptide substrate, proly-phenyl-alanyl-arginine-4-methylcoumaryl-7-amide (Pro-Phe-Arg-MCA). Using 20 microliters of normal urine, kallikrein activity was quantitatively assayed by incubation with a final concentration of 10(-4) M Pro-Phe-Arg-MCA at 37 degrees C for 90

A method was developed for the purification of kallikrein from human urine. The procedure consisted of three steps: ultradialysis, diethyl-(2-hydroxypropyl) aminoethyl (QAE) ion exchange radial flow membrane chromatography and affinity chromatography on aprotinin agarose. It is simple and suitable for

Polyreactive and thyroglobulin (Tg)-directed proteolytic activities present in the serum IgG of healthy controls and patients with autoimmune disease were studied by electrophoretic separation of 125I-labeled Tg reaction products and spectrofluorometric measurement of Pro-Phe-Arg-methylcoumarinamide cleavage at the Arg-methylcoumarinamide bond.
