Recombinant Human Immunoglobulin lambda constant 7 (Ig lambda-7 chain C region) fragment (amino acids 1-106) is a high-purity protein designed for studying the Ig-like domain. This product enables researchers to investigate the structural and functional roles of the constant region in antibody-mediated immunity, providing a reliable tool for immunological and biochemical applications.

Immunoglobulin lambda constant 7 is part of the constant region of immunoglobulin light chains, which are glycoproteins produced by B lymphocytes. These immunoglobulins function as membrane-bound receptors or secreted antibodies, playing a critical role in humoral immunity. Membrane-bound forms act as antigen-specific receptors on B cells, triggering clonal expansion and differentiation into antibody-secreting plasma cells upon antigen binding. Secreted immunoglobulins mediate effector functions, leading to antigen elimination. The antigen-binding site is formed by the variable domain of a heavy chain paired with its as
