Pepstatin A-agarose is used in protein chromatography, affinity chromatography and specialty resins. Pepstatin A-agarose has been used to characterize three chitosanase isozymes isolated from a commercial crude porcine pepsin preparation.

Aspiration of gastric contents by endotracheally intubated patients is associated with significant morbidity and mortality. Previous studies suggest that pepsin in tracheal aspirates may be a valuable marker of occult aspiration. We sought to show the sensitivity and specificity of

B lymphocytes from patients with I-cell disease (ICD) maintain normal cellular levels of lysosomal enzymes despite a deficiency of the enzyme UDP-N-acetylglucosamine: lysosomal enzyme N-acetylglucosamine-1-phosphotransferase. We find that an ICD B lymphoblastoid cell line targets about 45% of the lysosomal

Three chitosanases designated PSC-I, PSC-II, and PSC-III were purified from commercial pepsin preparation by sequentially applying pepstatin A-agarose affinity chromotography, DEAE-Sephacel ion-exchange chromatography, Mono Q column chromatography, and Mono P chromatofocusing. With respect to chitosan hydrolysis, the optimal pHs were
The pregnancy-associated glycoproteins (PAGs) are a large gene family expressed in trophoblast cells of ruminant ungulates. The detection of PAGs (more specifically, PAG-1) in maternal serum has served as the basis for pregnancy detection in cattle. Unfortunately, PAG-1 and/or antigenically-related

Aspartyl proteinase (AP) is an extracellular enzyme of Candida albicans implicated as a pathogenic factor. Previous reports on the purification and characterization of AP suggested that a single DEAE-Sephadex chromatographic step was sufficient for the removal of extraneous proteins and
