Normal human serum subjected to sucrose density gradient analysis exhibited multiple sedimenting species of properdin antigen. Properdin antigen distribution was dependent on serum concentration, ionic strength, temperature, and the presence of C3, a

As shown earlier, zymosan particles incubated with human citrated plasma develop the ability to induce a release reaction in platelets. Thus when incubated zymosan is shaken for 4 to 15 min with human citrated platelet-rich plasma, ADP, ATP, and 14C-

SummaryGranule enzymes were obtained from human peripheral blood leukocytes and added to HeLa cells growing as monolayers. The enzymes disrupted the monolayer, releasing the HeLa cells, but the released cells remained vital as determined by five sepa

Proteinases derived from Serratia marcescens and group A, β-hemolytic Streptococcus are each able to generate, by cleavage, leukotactic fragments from human C3 and C5. In whole human serum, the Serratia enzyme produces a C3-related leukotactic facto

Summary Heat-labile factors, resembling C′1 and C′2, and a hydrazine-sensitive factor resembling C′4 are required for the inactivation of C′3 by zymosan. Certain similarities exist between the interaction of C′ with zymosan and with sensiti

Summary Mg++ is required for the inactivation of C′3 by insoluble residues of yeast cells (zymosan). The concentration of Mg++ in normal serum is more than adequate for the reaction to proceed optimally. The requirement for Mg++ is also demonstrate

Purified streptococcal proteinase and Serratia proteinase are potent permeability factors in rat skin and initiate histopathological evidence of an acute inflammatory response. These effects appear to be largely independent of terminal components of

Limited proteolysis of the third component of human complement (C3) was performed by using trypsin and streptococcal proteinase and the digests were analyzed for biologic activity. Incubation of C3 with trypsin for 1 min yielded a peptide with smooth
