Description:
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.

Rabbit polyclonal to CPN1 (N-term)
Supplier:
MP Biomedicals
Description:
A vitamin/enzyme cofactor found in milk, eggs, malted barley, liver, kidney, heart, leafy vegetables. Richest natural source is yeast. Occurs in the free form only in the retina of the eye, in whey, and in urine; bioactive forms occurring in tissues and cells are riboflavin monophosphate and flavine-adenine dinucleotide.
Used as a photoinitiator for polymerization of polyacrylamide gels. It forms free radicals in aqueous solution in the presence of light. Riboflavin photodecomposes to leucoflavin. No free radicals are formed in the absence of oxygen but traces of oxygen allows for leucoflavin to reoxidize with free-radical generation. The catalysts TEMED or DMAPN are commonly added to speed up the free radical formation. The free radicals will cause acrylamide and bis-acrylamide to polymerize to form a gel matrix which can be used for electrophoresis. Riboflavin is commonly used in the stacking gel for non-denaturing polyacrylamide electrophoresis because native proteins can be senstive to persulfate ions from ammonium persulfate. Another advantage of riboflavin over ammonium persulfate is that it will not start polymerization until the gel is illuminated.
Riboflavin causes less denaturing than other initiators. Gel strength can be improved when used with PTO (Pyrithione). Soluble in 0.1 M Sodium Hydroxide (50 mg/ml - clear, yellowish-orange solution); only slightly soluble in water.
