CAS No.: 146797-82-2
Arachidonoyl Thio-PC is a substrate of many phospholipase A2 (PLA2), including sPLA2, cPLA2 and iPLA2. Cleavage of sn-2 fatty acids by PLA2 results in the production of free thiols, which react with chromogenic reagents such as DTNB (Ellman's reagent) and DTP, allowing quantification of PLA2 activity. Isozyme-specific cPLA2 activity can be measured by depleting or inhibiting sPLA2 and iPLA2 activity in the assay.

Cat. No.: HY-W009458
CAS No.: 3318-43-2
Synonyms: 3-IP sodium
3-Indoxyl phosphate (3-IP) is a chromogenic and electrochemical substrate for alkaline phosphatase. Upon enzymatic cleavage by alkaline phosphatase, 3-indoxyl is released and subsequently oxidized to produce water-insoluble indigo, which can be quantified by colorimetric detection at 660 nm as a measure of alkaline phosphatase activity. 3-Indoxyl phosphate can also be converted to water-soluble leucoindigo by reduction of indigo in alkaline solution by sodium dithionite, which can be quantified by colorimetric detection at 415 nm or voltametric detection as a measure of alkaline phosphatase activity.2 3-Indoxyl phosphate has been used in ELISAs.
