a chemical conjugate of normal mouse IgM
and the ribosome-inactivating protein, saporin

This product serves as a control for mouse IgM-containing immunolesioning agents (like Anti-M-ZAP). It is the same molecular weight, consists of comparable materials (saporin and a mouse IgM) and is synthesized with the same protocol as the targeted immunotoxins. The difference is the cell-specific antibodies are replaced with "blanks," antibodies that have no specificity, and no ability to target cells.

Effective Tool

• The perfect control molecule for immunolesioning agents
• There's no mixing of reagents; use it "as is" out of the vial
• No complicated calculations; use the same amount as the targeted toxin
• Ready to use: it comes sterile-filtered in phosphate-buffered saline
• It has the activity of non-targeted saporin, that is, almost none
