Optimal dilutions/concentrations should be determined by the end user. Target Relevance There are only two types of light chain: kappa and lambda in mammals. Other types of light chains are found in lower vertebrates as the Ig-Light-Iota chain in Chondrichthyes and Teleostei. In each antibody, only one type is present and the two chains are identical. Each light chain has two successive domains: one constant and one variable domain. In humans 60% of light chains are kappa and 40% lambda,whereas in the mouse 95% of light chains are kappa. The amino acid sequences of lambda chains vary slightly at a few positions, allowing them to be classified into subtypes. The number of subtypes varies between species. Monoclonal immunoglobulin free light chains (FLC) are found in the serum and urine (Bence-Jones protein) of patients with a number of B-cell proliferative disorders, including multiple myeloma. Changes in serum FLC concentrations can provide a rapid and sensitive indication of response to treatment. Cellular localization Cell Membrane: single-pass type I membrane protein and Secreted Anti-Human Ig light chain antibody [7A9] images IHC image of Human Ig light chain staining in human spleen formalin fixed paraffin embedded tissue section, performed on a Leica Bond system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab1942, 5µg/ml, for 15 mins at Immunohistochemistry (Formalin/PFA-fixed room temperature and detected using an paraffin-embedded sections) - Anti-Human Ig light HRP conjugated compact polymer system. chain antibody [7A9] (ab1942) DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
