Apolipoprotein B, the polypeptide moiety of human serum low density lipoprotein, is subject to degradation (as evidenced by sodium dodecyl sulfate-polyacrylamide gel electrophoresis) both in the intact particle and after delipidation. Protease inhibitors, sodium azide, and nitrogen saturation did not influence the rate or degree of degradation. Lipid-free apolipoprotein B prepared by gel exclus...

This study investigated calcium sulfate and chitosan on the textural modification microstructure of tofu made from lentils. The addition varying amounts (0–12 mM) (0–1.0%) into lentil milk could affect gel properties lentil-based tofu. properties, including hardness cohesiveness, significantly increased with 12 mM sulfate, exhibiting a slightly discontinuous network structure regular pore netwo...

Several properties of Haemophilus influenzae outer membrane proteins were analyzed to define related proteins in various isolates. H. influenzae type b 760705 had six major outer membrane proteins with the following characteristics. Protein a (Mr, 47,000) demonstrated heat modifiability in sodium dodecyl sulfate; its apparent molecular weight was 34,000 at temperatures below 60 degrees C. This ...

Reaction of leucine aminopeptidase with dimethyl suberimidate at pH 8.5 and room temperature, followed by incubation with sodium dodecyl sulfate and mercaptoethanol and then electrophoresis in 3.5% acrylamide gels resulted in six protein bands with molecular weights as integer values of 56,000. Under reaction conditions where appreciable crosslinking took place, the species corresponding to dim...
