生物活性
3-CPs 是可以干擾抗體介導(dǎo)的細(xì)菌殺傷的血清型莢膜多糖。體外研究
3-CPs displays protective effect against UVB damage in all concentrations tested. About 50% inhibition of bacterial killing is observed when 12 ng of purified type 3 CPS is added to the OPKA. The addition of 30 μL of mouse serum post-i.p. infection with WU2 (containing 0.4 to 0.7 μg/mL released type 3 CPS) shows 26% to 52% inhibition of bacterial killing, comparable to what is observed when an equivalent amount of purified CPS is added.
