| SpCrossreactivity | Specificity of antibodies has been tested using IEP, immunodiffusion, and ELISA. The antibodies yielded a single precipitin arc against anti-Rat serum and Rat IgM. No antibody reactivity is detected to other Rat serum proteins, IgA and IgG. Anti-Rat IgM may crossreact with IgM from other species. |
