Biotinylated Rabbit Anti-Rat IgG, mouse adsorbed, is supplied in lyophilized form and can be reconstituted with 1 ml water. With some exceptions the recommended dilution for most applications is 1:100.This specially prepared antibody is designed to be used on tissues that may contain interfering endogenous immunoglobulins. The mouse adsorbed anti-rat IgG (H+L) products have been thoroughly adsorbed by a solid phase technique to remove antibodies that cross-react with mouse immunoglobulins. This adsorbed antibody allows primary antibodies made in rat to be used on mouse tissues.
