Vector M.O.M. Immunodetection Kits are specifically designed to reduce endogenous mouse Ig staining when using mouse primary antibodies on mouse tissue. This problem can be essentially eliminated by using Vector M.O.M. technology. The result is clear, crisp specific staining of the antigens of interest. This Vector M.O.M. ImmPRESS Kit contains our proprietary M.O.M. Mouse Ig Blocking Reagent paired with a specialized, ready-to-use, one-step M.O.M. ImmPRESS Peroxidase Polymer reagent. The highly active peroxidase micropolymers of the ImmPRESS Detection System provide outstanding sensitivity, limit steric interference, and enhance accessibility. Contains sufficient reagents to stain approximately 150 mouse sections. Includes 0.6 ml M.O.M. Mouse Ig Blocking Reagent (concentrate), 30 ml R.T.U. 2.5% Normal Horse Serum, and 15 ml R.T.U. M.O.M. ImmPRESS Anti-Mouse Ig Reagent.
