Detection of Human Immunoglobulin Lambda Constant Region by Western Blot. Western blot shows lysates of RPMI 8226 human multiple myeloma cell line. PVDF Membrane was probed with 1 µg/mL of Human Ig lambda C Domain Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6525) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for Immunoglobulin lambda constant region at approximately 25 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: Ig Lambda C Domain
Immunoglobulin lambda constant region is a Ke-Oz- component of immunoglobulin (Ig) lambda light chains and is found C-terminal to the joining region of the light chain. IGLC2 is 105 amino acids (aa) in length. It contains one Ig-like domain (aa 7-100) and generates a disulfide bond with an IgH chain via Cys104. One potential variant shows a three aa substitution for aa 7-9. The closest mouse lambda ortholog shares 61% aa identity with full-length human IGLC2. IGLC2 shares 93 - 98 % aa identity with IGLC1, IGLC3 and IGLC7.
