Enzyme Substrates

TEV protease kit that may be used for cleaving proteins or peptides containing the TEV protease recognition sequence E-N-L-Y-F-Q↓(S/G/A/M/C/H).

10-Acetyl-3,7-dihydroxyphenoxazine (Amplex® Red), is regarded as the best fluorogenic substrate for peroxidase and H₂O₂ because it is highly sensitive, specific and stable.

ABTS (2,2′ -Azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid), diammonium salt) is a very sensitive chromogenic peroxidase substrate widely used for ELISA applications. The substrate yields a water-soluble green colored product.

Ac-DEVD-AMC is a fluorogenic substrate for caspase 3 and can be used to continuously measure the activity of caspase-3 in cell extracts, using a fluorometer or fluorescence microplate reader. For real-time detection of caspase-3 activity in intact cells, see our novel NucView®488 Caspase-3 Assay Kit.

Z-IETD-R110 is a substrate for caspase-8, which is involved at the early stage of apoptosis, acting as an initiator of the caspase activation cascade.

A pink derivative of BCIP that produces a pink colored (λ_max 540 nm) precipitate instead of the dark blue precipitate of BCIP. BCIP and derivatives are the most widely used chromogenic phosphatase substrate for the detection of alkaline phosphatase labeled proteins and are compatible with a variety of applications.

NBT and BCIP PINK are widely used together as a chromogenic phosphatase substrate for the detection of alkaline phosphatase labeled proteins in a variety of applications, such as immunohistochemistry, westerns, and in situ hybridization. This kit contains 100 mg each of BCIP Pink (10006) and the precipitation inducer NBT (10008).

A red derivative of BCIP that produces a red (λ_max 565 nm) colored precipitate instead of the blue/violet precipitate of BCIP. BCIP and derivatives are the most widely used chromogenic phosphatase substrate for the detection of alkaline phosphatase labeled proteins and are compatible with a variety of applications.

A red derivative of BCIP that produces a red (λ_max 565 nm) colored precipitate instead of the dark blue precipitate of BCIP. BCIP and derivatives are the most widely used chromogenic phosphatase substrate for the detection of alkaline phosphatase labeled proteins in a variety of applications.

A water soluble formulation of the most widely used chromogenic phosphatase substrate for the detection of alkaline phosphatase labeled proteins in a variety of applications, such as immunohistochemistry, westerns, and in situ hybridization.

The most widely used chromogenic phosphatase substrate for the detection of alkaline phosphatase labeled proteins in a variety of applications, such as immunohistochemistry, westerns, and in situ hybridization. This form is soluble in DMF.

BCIP/NBT are widely used together as a chromogenic phosphatase substrate for the detection of alkaline phosphatase labeled proteins in a variety of applications, such as immunohistochemistry, westerns, and in situ hybridization. This kit contains 100 mg each of BCIP sodium salt (10001) and the oxidant NBT (Nitro blue tetrazolium, 10008).

BZAR (Rhodamine 110, bis-(N-CBZ-L-arginine amide), dihydrochloride) is a substrate for serine proteases (1-5) and is also an inhibitor for quanidinobenzoatase. It is 50 to 100 times more sensitive than the AMC-based substrate.

BZiPAR (Rhodamine 110, bis-(N-CBZ-L-isoleucyl-L-prolyl-L-arginine amide), dihydrochloride) is a substrate for trypsin (1,2). The substrate has been reported to enter live cells and be hydrolyzed by lysosomal proteases (3).
