Supplier: Thermo Fisher Scientific

This Micrococcal Nuclease (MNase) is suitable for removing nucleic acids from cell lysates, releasing chromatin-bound proteins and shearing chromatin for use in chromatin immunoprecipitation (ChIP) experiments.

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.

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

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: Merck Millipore (Novagen)

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: Merck Millipore (Calbiochem‎)

Native endoproteinase Glu-C from Staphylococcus aureus. Serine protease that specifically hydrolyses peptide bonds at the carboxylic side of glutamic acid and aspartic acid residues. Inhibited by DFP and α2-macroglobulin. Suggested working concentration: 1:20 to 1:100 (protease:protein by weight) for sequence analysis.

Supplier: Merck Millipore (Calbiochem‎)

Native endoproteinase Asp-N from Pseudomonas fragi. Designed for protein sequencing or sequence verification, analysis of protein structural domains, and cleavage of fusion proteins. Metalloprotease that specifically hydrolyses proteins at the N-terminal side of aspartic acid and cysteic acid residues. Inhibited by aprotinin, DFP, leupeptin, and TLCK. Suggested working concentration: 1:20 to 1:100 (protease:protein by weight) for sequence analysis.

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.

Supplier: Promega

Wheat germ extract contains the cellular components necessary for protein synthesis (tRNA, ribosomes, initiation, elongation and termination factors).

Supplier: Promega

rLys-C, MS grade, is a recombinant Lys-C expressed in E. coli. It cleaves at C-terminus of lysines.

Supplier: Promega

FastBreak™ cell lysis reagent is provided as a 10X concentrate and contains a proprietary non ionic detergent to facilitate lysis. Recombinant proteins can be directly screened in the cell extract or purified by the addition of the appropriate affinity matrix such as the MagneHis™ protein purification system.

Supplier: Promega

ProteaseMAX™ Surfactant ensures fast and efficient protein digestion with proteases such as trypsin, chymotrypsin and Lys-C.

Supplier: Promega

Endoproteinase hydrolyses peptide bonds on the N-terminal side of aspartic and cysteic acid residues (Asp and Cys).

Supplier: Promega

Rabbit Reticulocyte Lysate, Untreated contains the cellular components necessary for protein synthesis (tRNA, ribosomes, amino acids, initiation, elongation and termination factors) but has not been treated with micrococcal nuclease. Untreated Lysate is used primarily for the isolation of these components and as an abundant source of endogenous globin mRNA.

Supplier: Promega

Arg-C, sequencing grade, is an endopeptidase (clostripain) that cleaves at the C-terminus of arginine residues, including the sites next to proline and it occurs also at proline.

Supplier: Promega

Trypsin/Lys-C mix improves peptide digestion over trypsin alone, increasing peptide recovery and resulting in better protein quantitation by using standard digestion conditions.

Supplier: Promega

Glu-C sequencing grade serine protease (S. aureus V8) specifically cleaves at the C-terminus of either aspartic or glutamic acid residues.

Supplier: Promega

Trypsin Gold, mass spectrometry grade, has been manufactured to provide maximum specificity. Lysine residues in the porcine trypsin have been modified by reductive methylation, yielding a highly active and stable molecule that is extremely resistant to autolytic digestion. The specificity of the purified trypsin is further improved by TPCK treatment, which inactivates chymotrypsin. The treated trypsin is then purified by affinity chromatography and lyophilised.
