ActiveHOOK™HyperCarrier™ is maleimide activated HyperCarrier™, by the addition of sulfoSMCC cross-linker. The ActiveHOOK™HyperCarrier™ rapidly couples to free sulfhydryl groups on peptides and proteins. This activated carrier proteins save both time and money as separate cross-linkers are not required and the reaction is a one step reaction. HyperCarrier™ is normal BSA that has been treated with ethylene diamine, which substitutes anionic carboxyl groups with cationic aminoethyl-amide groups. This cationized form stimulates a higher immunogenic response, compared to normal BSA, and allows for a greater concentration of coupled peptides. ActiveHOOK™ HyperCarrier™is available as a 10mg vial or as our OneQuant™ single use line as 8 x 2mg vials.
