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.

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

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

The intestinal epithelium forms a first line of innate host defense by secretion of proteins with antimicrobial activity against microbial infection. Despite the extensive studies on the antimicrobial host defense in many gastrointestinal tracts, little is known about the antimicrobial
