Supplier: G-Biosciences

A proteolytic enzyme immobilised on 4% agarose that is routinely used for the generation of F(ab’)₂ fragments from Immunoglobulin G (IgG). The pepsin has the ability to cleave the heavy chains near the hinge region. The immobilised Pepsin offers the distinct advantage of eliminating enzyme contamination of the F(ab)₂ fragments.

The carbonyl-reactive Thermo Scientific™ aminoxyTMT™ (Tandem Mass Tag™) Label Reagents enable multiplexed characterisation and quantitation of carbonyl-containing biomolecules (carbohydrates, steroids, oxidised proteins) by mass spectrometry (MS).

Supplier: Thermo Fisher Scientific

SDS-Out™ SDS Precipitation Kit provides convenient removal of SDS from small-volume (0,1 to 10 ml) protein samples.

Supplier: Thermo Fisher Scientific

Surfact-Amps™ Detergent sampler is a collection of various Surfact-Amps™ detergent solutions and selected other useful detergents for protein research methods.

Supplier: Thermo Fisher Scientific

Pierce™ immobilised TPCK trypsin is a serine endoprotease applicable to amino acid analysis and protein sequencing, mapping and structural studies. The immobilised form allows sample separation after treatment.

Supplier: Thermo Fisher Scientific

The HiPPR™ Detergent Removal Spin Column Kit improves mass spectrometry results by efficiently removing detergents from 25 to 200 µl samples with low protein or peptide concentrations.

Supplier: G-Biosciences

A cysteine protease enzyme (EC 3.4.22.2) immobilised on 4% agarose, cleaves Immunoglobulin G (IgG) antibody molecules in the hinge region, generating three ~50 kDa fragments; two Fab domains and a Fc domain. The papain-digested antibody is unable to promote agglutination, precipitation, opsonisation, and lysis.

Supplier: G-Biosciences

Trypsin is a serine endopeptidase that specifically cleaves peptide bonds on the carboxy side of s-aminoethyl cysteine, arginine and lysine residues and typically there is little or no cleavage at arginyl-proline and lysyl-proline bonds. The distribution of these residues in proteins allows trypsin digestion to produce peptides that are readily identified by mass spectrometry.

The CytoBuster™ protein extraction reagent is a proprietary formulation of detergents optimised for efficient extraction of soluble proteins from mammalian and insect cells. The gentle, non-ionic composition of the reagent enables isolation of functionally active endogenous or expressed proteins without a need for secondary treatment such as sonication or freeze/thaw.

Supplier: Merck Millipore (Novagen)

BugBuster® master mix combines BugBuster® protein extraction reagent with Benzonase® Nuclease and rLysozyme™ solution in one convenient reagent. It allows for maximum recovery of active soluble protein from both Gram-negative and Gram-positive bacteria. The master mix provides sufficient reagents for protein extraction from 20 g and 100 g cell paste.

Supplier: Merck Millipore (Novagen)

PopCulture® Reagent is a detergent-based concentrate that can be added directly to cultures of E. coli to effectively extract proteins without the need for cell harvest. Recombinant proteins can be directly screened in the crude extract, or purified by adding an affinity matrix, washing the matrix-target protein complex to remove spent culture medium and cellular contaminants, and eluting the purified protein from the matrix. The PopCulture protein purification procedure is ideally suited to high-throughput robotic processing of samples for proteomics research or any application that would benefit from the increased speed and convenience.

Supplier: G-Biosciences

Protein-OUT™ is a washing solution that cleans plastic and glassware used in the proteolytic digestion and peptide isolation for mass spectrometry analysis. The rinsing of plastic and glassware with Protein-OUT™ will remove interfering chemicals and peptides that can leach from the tube walls and interfere or suppress the mass spectrometry signal. In addition, rinsing with Protein-OUT™ removes inadvertent contamination with dust and keratin.
