2,2-Azino-bis-(3-ethyl-benzthiazoline-6-sulfonic acid) (ABTS) has been used as a chromogenic substrate for horseradish peroxidase (HRP), both in general activity assays and in ELISA applications. Activity of HRP using ABTS appears about four-fold higher than using pyrogallol. It is mainly used as a substrate in sensitive peroxidase assays.
2,2′-Azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) is a peroxidase substrate suitable for use in ELISA procedures. This substrate produces a soluble end product that is green in color and can be read spectrophotometrically at 405 nm. The reaction may be stopped with 1% sodium dodecyl sulfate (SDS). Recommended for ELISA (microwell) procedures, not recommended for membrane applications.

SDS is an anionic detergent and wetting agent that is effective in both acid and alkaline solutions.
Used to solubilize and denature proteins for denaturing-PAGE. Most proteins bind SDS in a ratio of 1.4 g SDS per gram of protein. The charges intrinsic to the protein become insignificant compared to the overall negative charge provided by the bound SDS. The charge to mass ratio is essentially the same for each protein and will migrate in the gel based only on their size.

Autoimmune hemolytic anemia (AIHA) is an autoimmune disease characterized by antibody coated red blood cells that either lyse in the presence of complement, or are subject to phagocytosis by the liver and spleen, resulting in a severe anemia. Equine anti-Globulin reagent has been widely used for the diagnosis of autoimmune hemolytic anemia (AIHA) in a variety of species. Although not common AIHA has been reported in the horse. Equine anti-globulin reagent is also useful in the neonatal isoerythrolysis test. The anti-globulin procedure has also been used in equine blood typing.
