QUICK LINKS

Pertussis Toxin (islet-activating protein), a toxin that can be found in Bordetella pertussis, may act to catalyze ADP-ribosylation of a protein in membrane preparation from rat C6 glioma cells. In addition, exposure of Chinese hamster ovary cells in culture to this compound has resulted in a clustered growth pattern response. Other experiments have shown Pertussis Toxin (islet-activating protein) to block the ability of inhibitory hormones to reduce adenylate cyclase activity and enhance the ability of stimulatory hormones to activate the enzyme. Mechanistic studies have shown this toxin to consist of subunit A (active) promoter, which disrupts transmembrane signaling by ADP-ribosylating eukaryotic G-proteins, and B (binding) oligomer which helps the toxin bind to cells in vivo.

hi just need to know molecular weight of this pertussis, because i want to dilute to have 200 ng/ml thank you

Asked by: smel2377
Thank you for your question. The molecular weight is lot dependent, but here is a link to a recent CoA, which contains the molecular weight information. https://datasheets.scbt.com/coa/coa.php?sc=sc-200837&lot=F1119
