Human urinary kallikrein (urokallikrein) has been purified by affinity chromatography with aprotinin coupled to CH-Sepharose and by gel filtration. The isolation procedure, which was performed under mild conditions, was completed in a 36-hr period and yielded an overall recovery of more than 75% and a purification of 1727-fold. Homogeneity of the urokallikrein was demonstrated by three criteria...

Human lymphoblastoid interferon was produced on an 800-liter scale (2.6 X 10(9) units) by induction of Namalva cells with Newcastle disease virus, strain B1. The interferon was partially purified by anti-leukocyte interferon affinity chromatography, sulfopropyl Sephadex ion exchange chromatography, isoelectric focusing, and sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Recovery of ...

Microsomal UDP-glucuronosyltransferase activity toward chenodeoxycholic acid and testosterone has been isolated from rat liver and appears to be homogeneous in sodium dodecyl sulfate gel electrophoresis and polyacrylamide gradient gel electrophoresis. The conjugating activities toward chenodeoxycholic acid and testosterone co-purified and showed identical mobilities in disc gel electrophoresis,...

Advanced BioMatrix offers a large number of extracellular matrix (ECM) and three dimensional (3D) scaffold products with one of the most extensive Type I collagen product offerings (see Exhibit 1). One analytical method for evaluating the quality, purity and consistency of the products is Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS PAGE electrophoresis). The purpose of the do...

Protein profile change of Bulgarian Chardonnay wine under the influence treatment with bentonite was studied. concentration determined using Bradford assay, while fractionation performed via sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The amount protein found in original 147.1 mg/dm3, expressed as bovine serum albumin divided into 9 electrophoretic fractions. Low molecular weight...

Glutamate dehydrogenase (GDH) has been purified from beef heart mitochondria and compared with crystalline beef liver GDH. The specific activity of heart GDH was 127 units and of liver GDH 80 units. Heart GDH subjected to sodium dodecyl sulfate-polyacrylamide gel electrophoresis had a protein corresponding to liver GDH and a smaller molecular weight protein. On agarose gel electrophoresis heart...
