Molarity Calculator

Delta-hemolysin (Delta-lysin), a 26 amino acid peptide, is a hemolytic peptide produced by Staphylococcus. Delta-hemolysin may slightly perturb a membrane or lead to cell lysis. Delta-hemolysin is a model in the study of peptides interacting with membranes. Delta-hemolysin is poorly active against bacteria.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
