In vitro study	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.

(IARC) carcinogen classification	3 (Vol. 40, Sup 7) 1987
EPA chemical substance information	information provided by: ofmpeb.epa.gov (external link)
biological activity	3-CPs are serotype capsular polysaccharides that can interfere with antibody-mediated bacterial killing.
