The kallikrein world: an update on the human tissue kallikreins.
Human tissue kallikreins (hKs) are attracting increased attention owing to their association with various forms of cancer and other diseases. Human tissue kallikrein genes represent the largest contiguous group of proteases within the human genome. There are many areas of kallikrein research that need to be further explored, including their tissue expression patterns, their regulation, identifi...
متن کاملIdentification, purification, and localization of tissue kallikrein in rat heart.
A tissue kallikrein has been isolated from rat heart extracts by DEAE-Sepharose and aprotinin-affinity column chromatography. The purified cardiac enzyme has both N-tosyl-L-arginine methyl ester esterolytic and kinin-releasing activities, and displays parallelism with standard curves in a kallikrein radioimmunoassay, indicating it to have immunological identity with tissue kallikrein. The enzym...
متن کاملPurification and characterization of a kallikrein-like T-kininogenase.
A T-kininogenase has been purified to homogeneity from rat submandibular gland extracts by DEAE-Sepharose chromatography and preparative gel electrophoresis. The purified protein has an apparent Mr of 28,000 on sodium dodecyl sulfate-polyacrylamide gel electrophoresis and splits into heavy and light chains with Mr of 22,000 and 6,000 in the presence of dithiothreitol. It is an acidic glycoprote...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Improved purification of rat intestinal lactase.
A rapid and improved method to obtain purified lactase from rat intestine is described. The purification procedure involved only two chromatographic steps. The degree of purification was far above (500 fold) the values reached with classical methods. Rabbit antisera raised to the purified lactase were characterized using conventional immunological techniques. The specificity of the lactase anti...
