Fluorescein Horse Anti-Mouse IgG (H+L) Antibody, rat adsorbed, can be used for flow cytometry or for tissue staining. Optimal F/P ratios have been established for each conjugate to ensure maximum fluorescence with minimal background staining. Maximum excitation is at 495 nm and maximum emission is at 515 nm. This specially prepared antibody is designed to be used on tissues that may contain interfering endogenous immunoglobulins. The rat adsorbed anti-mouse IgG (H+L) products are designed for use with rat tissues that may contain endogenous rat immunoglobulins. This adsorbed antibody allows primary antibodies made in mouse to be used on rat tissues.
