Recombinant streptavidin from streptomyces avidinii, produced in E.coli. Biotin, a 244Da vitamin (Vitamin H) molecule, exhibits an extraordinary binding affinity for streptavidin (Ka=10 15 M -1 ). Biotin and streptavidin interaction is rapid and once the bond is established it can survive up…

Active HOOK ™ BSA is maleimide activated BSA, by the addition of sulfoSMCC cross-linker. The Active HOOK ™ BSA 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…

G-Biosciences Non Animal Protein Standards are protein standards for use in protein estimations that are generated from non-animal proteins. The prediluted Non Animal Protein Standards are ready to use solutions prepared in an aqueous buffer with a preservative for product stability. They are…

Calmodulin, Recombinant Human is a full length (Met1- lys149, Accession # P62158) human recombinant calmodulin protein expressed in E. coli . Calmodulin is a ubiquitous calcium- binding protein present in all eukaryotic cells and some cell organelles. Calmodulin plays a pivotal role in calcium…

Bovine serum albumin is a single polypeptide of 67kDa and consists of 59 lysine residues, of which 30-35 have primary amines that can react with crosslinkers for the coupling of peptides. OneQuant ™ BSA The BSA carrier protein is also available as our single use OneQuant ™ vials…

Active HOOK ™ KLH is maleimide activated by the addition of sulfoSMCC cross-linker. The Active HOOK ™ KLH 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…

G-Biosciences’ Jacalin ( Artocarpus integrifolia lectin) is isolated from the seeds of jackfruit and purified by affinity chromatography. Jacalin is a α-D-galactose binding lectin consisting of a tetrameric two chain structure with a molecular weight of ~66kDa. Jacalin, due to its…

We offer two opitions for the Bovine γ-globulin standards: Bovine γ-Globulin Standard γ-Globulin standard (2mg/ml) prepared in saline buffer. Supplied as 2 x 5ml size. Prediluted γ-Globulin Protein Standards γ-Globulin protein standards in an…

HyperCarrier ™ is normal BSA that has been treated with ethylene diamine, which substitutes anionic carboxyl groups with cationic aminoethyl-amide groups. Researchers were able to demonstrate that a cationized form of BSA, produced by replacing anionic side chain carboxylic groups with…

Keyhole limpet hemocyanin is a widely used carrier protein due to its large molecular mass (4.5x10 5 -1.3x10 7 Da aggregates) and large number of primary amines that can react with cross-linkers for the coupling of peptides. The KLH is supplied as a clear to slightly hazy, bluish solution in…

Active HOOK ™ HyperCarrier™ is maleimide activated HyperCarrier™, by the addition of sulfoSMCC cross-linker. The Active HOOK ™ HyperCarrier™ rapidly couples to free sulfhydryl groups on peptides and proteins. This activated carrier proteins save both time and money as…
