For immunohistology and flow cytometry dilutions to be used depend on detection system applied. It is recommended that users test the reagent and determine their own optimal dilutions. The typical starting working dilution is 1:10. Advised positive controls for frozen sections are human lymphnodes and for flow cytometry PHA activated T cells.
The antibody MR1-2 reacts with the extra-cellular part of the TNF-R I. It also reacts with the soluble receptor. TNF-R I is present on most cell types and is considered to play a prominent role in cell stimulation by TNF-alpha: Induction of cytotoxicity and other functions are mediated largely via TNF-R I. The antibody cross reacts with rhesus and cynomolgus natural TNF-R I.
