Enzyme ImmunoAssay (EIA) is a technique to detect and quantify antigens (proteins, hormones…) or antibodies in samples. It relies on the ability of an antibody to bind a specific antigen. Either the antibody or the antigen is labelled with an enzyme whose substrate is a chromogen or a fluorogen converted in a measurable product (color or fluorescence).|Enzyme-linked Immunosorbent Assay (ELISA) is a type of EIA using a solid phase (ex: microtiter plate) coated with an antigen immobilizing the molecule to detect. Over the time, scientists have extended the term ELISA to EIAs using an antibody coating the solid phase. That explains why our EIA kits using coated antibodies are also called ELISA kits.|CCL3L1 is also known as Chemokine (C-C motif) ligand 3-like 1 or LD78b (1). It is an isoform of the CCL3 (Macrophage Inflammatory Protein-1alpha)(1) from the family of the Chemokine C-C motif.|This protein binds to several chemokine receptors including chemokine binding protein 2 (CCBP2 or D6) and chemokine (C-C motif) receptor 5 (CCR5).|Its main function is the chemiotactism for several different leukocytes. Due to its capacity to link to the receptor 5, CCL3L1 could play a function in the HIV infection(2).
