Enzyme Labeling Reagents for Proteins


Horseradish peroxidase (HRP), alkaline phosphatase (AP) and other substrate enzymes in purified, activated and kit formats for easy conjugation to proteins and preparation of antibody conjugates for immunoassay procedures.


Purified calf-intestinal alkaline phosphatase (AP, alk-phos) enzyme for use in activity assays and conjugation to antibodies for ELISA and IHC. 

Specially purified 50% ethylene glycol solution to provide antifreeze protection and freezer storage stability for antibody-enzyme conjugates. 

Protects the enzyme activity of horseradish peroxidase (HRP) conjugates, fully-stabilizing even very dilute (1 ng/ml) stock solutions.  

Purified horseradish peroxidase enzyme for use in activity assays and conjugation to antibodies for ELISA, Western blot and immunohistochemistry applications. 

Glutaraldehyde-activated horseradish peroxidase (HRP) enzyme and kit to label primary antibodies and purify the resulting antibody-HRP conjugates. 

Activated horseradish peroxidase (HRP) enzyme and kit to label proteins, peptides or other ligands via sulfhydryl groups (reduced cysteines) to make HRP conjugates. 

Periodate-aldehyde-activated horseradish peroxidase (HRP) enzyme and kit to label primary antibodies to obtain high-activity antibody-HRP conjugates. 

A gentle affinity system to purify enzyme-conjugated antibodies from unreacted horseradish peroxidase (HRP) or alkaline phosphatase (AP) after labeling. 

An antifreeze solution to store aliquots and stocks of HRP-conjugated antibodies so they can be pipetted for use without thawing; better than glycerol.
