Species on Species Detection

When your primary antibody is the same species as your specimen

When a primary antibody is made in the same species as your specimen, the secondary antibody cannot distinguish that primary antibody from endogenous immunoglobulins. This causes high background staining and obscures antigen-specific staining.

Use VECTOR^® M.O.M.^® (Mouse on Mouse) Kits to significantly reduce endogenous mouse Ig staining when using mouse antibodies on mouse tissue.

• Eliminate tedious calculations and primary antibody pre-binding steps
• See clear, crisp, specific staining
• Introduce two or more labels in a multiple antigen labeling protocol (detect several mouse primary antibodies on the same tissue section)

The VECTOR M.O.M. Kits:

• Contains proprietary M.O.M. Mouse IgG Blocking Reagent
• Employ either avidin-biotin or polymer technology
• Are compatible with fluorescent or enzyme-based detection
• Are available with or without enzyme or fluorochrome

You can have excellent staining results — for a once difficult application — with the VECTOR M.O.M. Kits.
