Antibodies - K2

K2 anti-dsRNA monoclonal antibody has an IgM isotype.

K2 is mainly used for specialised applications, where J2 and K1 - antibodies that can be shipped at ambient temperature - do not suffice. Due to its IgM isotype K2 is more prone to aggregation at high concentration, and therefore cannot be lyophilised and needs to be shipped on ice.

K2 has primarily been used in ELISA and sandwich ELISA. Generally, K2 can be used in applications where an anti-dsRNA antibody with an isotype other than IgG (IgG2a) is required.
