Product details:
Human SIGLEC6 ELISA Kit is designed for the quantitative determination of SIGLEC6 in cell culture supernatants, plasma and serum samples.
Δ Note:
Human SIGLEC6 concentration is low in normal serum/plasma and may not be detectable in this assay.
This assay employs an antibody specific for human SIGLEC6 coated on a 96-well plate. Standards and samples are pipetted into the wells and SIGLEC6 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-human SIGLEC6 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of SIGLEC6 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

SIGLEC6 also known as CD327 is a protein found on some immune cells particularly on B cells and to a lesser extent on macrophages and dendritic cells. This protein has a molecular mass of around 100 kDa. As a member of the sialic acid-binding immunoglobulin-type lectins family (siglecs) SIGLEC6 mechanistically functions by recognizing and binding to specific sialic acid-containing carbohydrates on cell surfaces. This recognition influences cell-cell interactions and signaling processes important for immune response modulation.
Biological function summary
SIGLEC6 serves as an inhibitory receptor that helps dampen B cell receptor signaling balancing the immune response to prevent overactivation. It often partners with other proteins in complex cellular interactions within the immune cells. The expression of SIGLEC6 in placental tissues also suggests a role in trophoblast invasion and development although this function requires more research to fully understand the mechanisms involved.
Pathways
SIGLEC6 is a part of the B cell receptor signaling pathway acting as an inhibitory modulator. Through this pathway it connects with proteins like CD22 and other siglecs that contribute to the regulation of B cell activity. Additionally its role in glycan recognition links it to pathways associated with cell surface interactions and immune tolerance.
SIGLEC6 expression alterations have implications in chronic lymphocytic leukemia (CLL) where it potentially influences disease progression by modulating B cell signaling. The protein has also been connected to gestational trophoblastic diseases potentially affecting placental development. In these contexts SIGLEC6 interacts with proteins such as CD22 in CLL where they collectively affect leukemic cell behaviors and disease outcomes.
