The analysis of gene expression is a common experiment conducted routinely in the laboratory. Profiling gene expression provides vlauable insight into genes involved in normal cell/tissue homeostasis, organisms development and…

protocol Elisa macrophages obtain Peritoneal macrophages from BALB/c Mice. 1) inject mice with 3 ml thioglycolate broth (encourages macrophages to come to cavity) 2) wait 4 days 3) inject PBS Split cells…
Enzyme-linked immunosorbent assay (ELISA), is a popular format of a "wet-lab" type analytic biochemistry assay that uses one sub-type of heterogeneous, solid-phase enzyme immunoassay (EIA) to detect the presence of a substance in a…
Latex aggluination: is a method for rpaidly measuring a substance to be analyzed, by visually or optically detecting a degreer of latex-particle-allutination caused by a reaction of the substance to be…
See also ABO blood group typing Hemagglutination is a general term applied to any agglutination test in which clumping of red blood cells indicates a positive reaction. Human blood can vary…
Agglutination Reactions are similar in principle to precipitation reactions in that they depend on the crosslinking of polyvalent antigens. Hemagglutination is used in blood typing. RBCs are mixed on a slide with…
Immunodiffusion Immunodiffusion takes advantage of the fact that antibody and antigen interact in aqueous solution to form a lattice that eventually develops into a visible precipitate. Antibodies that aggregate soluble…
A variety of enzyme systems operate to reveal a colorimetric signal in an assy. Such examples include glucose oxidase, perioxide and tetramethyl benzidine (TMB) system, and a horseradish peroxidase (HRP)…
