OneQuant carrier proteins eliminate waste while saving the laboratory time and money. Three immunological-grade protein carrier proteins are offered on the single-use OneQuant format. These proteins include BSA, KLH, and HyperCarrier, which is a cationized form of bovine serum albumin. OneQuant carrier proteins also are supplied as a preactivated form. These preactivated carrier proteins are activated with sulfoSMCC and are ready to be coupled to cysteine residues on the peptides.
