CSA II Rabbit Link is for use with polyclonal rabbit primary antibodies and the ultra-sensitive, biotin-free CSA II System, Code K1497. The CSA II System is intended for difficult, low-affinity primary antibodies of mouse origin and can be adapted for use with rabbit primary antibodies by replacing the peroxidase-conjugated secondary antibody in Code K1497 with the CSA II Rabbit Link, Code K1501. CSA II Rabbit Link is ready-to-use, peroxidase-conjugated goat anti-rabbit immunoglobulins. The number of tests is based on the use of 100 µL of reagent per test.
