The properties described are: (1) normal boiling point; (2) densities and partial molar volume of water in solution; (3) viscosities at different concentrations and temperatures, as compared with those of a typical nonelectrolyte, urea; (4) the temperature coefficient of fluidity compared with ...
Suffice it to say that the unusually high boiling point of acetic acid. 只要谈一下醋酸的不寻常的高沸点就行。 Separation and Purification of Organic Mixture and Its Mensuration of Boiling Point Under Ordinary Pressure; 常压下有机混合物的分离提纯及沸点测定 ...
p21-activated kinases (PAKs) are serine/threonine kinases functioning as downstream effectors of the small GTPases Rac1 and Cdc42. Members of the PAK family are overexpressed in human breast cancer, but their role in mammary gland development is not fully explored. Here we examined the functiona...

Teichoic acid (TA), a crucial cell wall constituent of the pathobiont Streptococcus pneumoniae, is bound to peptidoglycan (wall teichoic acid, WTA) or to membrane glycolipids (lipoteichoic acid, LTA). Both TA polymers share a common precursor synthesis pathway, but differ in the final transfer of...
Gels were stained with 0.5% Coomassie blue G250 in 30% methanol, 10% glacial acetic acid for 30 min and destained in the same solution without Coomassie blue. Gelatin-degrading enzymes were identified as clear bands against the blue background of the stained gel. Images of stained gels ...
