General description

Anti-Human κ Light Chain (bound and free) antibody is obtained from goat antiserum. Immunospecific purification removes all goat serum proteins and immunoglobulins that do not bind to the κ light chain (bound and free). Goat anti-κ light chain is conjugated to fluorescein isothiocyanate (FITC). The antibody preparation is specific for human κ light (human IgA, IgG, and IgM) and free κ light chain (Bence Jones κ myeloma protein). The conjugate shows no reaction with bound or free λ light chains.
Anti-Human Kappa Light Chain (Bound and Free)−FITC antibody is specific for human kappa light chain when tested against purified bound kappa light chain (human IgA, IgG, and IgM) and free kappa light chain (Bence Jones Kappa myeloma protein). The conjugate shows no reaction with bound or free lambda light chains.
Mammalian antibodies contain one of two types of light chain, called kappa or lamba. Each chain contains a constant and a variable domain. Mammalian antibodies contain either two kappa or two lambda light chains.
Fluorescein isothiocyanate (FITC) is a fluorescein derivative (fluorochrome) used to tag antibodies, including secondary antibodies, for use in fluorescence-based assays and procedures. FITC excites at 495 nm and emits at 521 nm.
