ABTS
Cat No.
CSUB-0406
Applications
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.ABTS (C18H16N4O6S4-(NH4)2) is a peroxidase substrate for ELISA.
