Agglutination assays
Introduction: Agglutination Reactions are similar in principle to precipitation reactions in that they depend on the cross-linking of polyvalent antigens. Hemagglutination is used in blood typing. RBCs are mixed on a…
Immuno assays
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…
flow cytommetry
Flow cytometry is a laser based technique used in many applications such as cell counting, sorting, and biomarker detection.
enzymatic assays
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)…
Fetal assays
See also chromatin structure Prenatal testing is often performed to determine the gender of the fetus or to detect genetic disorders and/or chromosomal abnormalities in the fetus during pregnance. Over…

density separation
All density separation techniques have the same basic limitation; they can not separate subpopulations of cells with overlapping density distributions such as human lymphocyte subsets. To address this, dense particles…
Lables & conjugation
A wide variety of labels and conjugation techniques are known and reported extensively in both the scientific and patent literature. Preferred detectable labels include, but are not limited to, a fluorescent…
detection assays
Imaging Assays Axworthy teaches methods that relate to delivery of diagnostic agents (abstract). In one embodiment, a chemical conjugate or fusion protein with streptavidin (first member of a binding pair)…
