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.

ProteoExtract® Kits cover the different steps of the proteomics workflow, from protein extraction and abundant protein removal to concentration of protein mixtures and removal of interfering substances, digestion of proteins and selective capturing of phosphopeptides. These kits work in concert with one another to provide protein samples that are directly compatible with downstream analytical applications.

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: Merck Millipore (Novagen)

BugBuster® Plus Lysonase™ includes BugBuster Protein Extraction Reagent and Lysonase Bioprocessing Reagent, an optimised, ready-to-use blend of rLysozyme™ and Benzonase® Nuclease in a single kit. This powerful combination of two reagents allows maximum recovery of active soluble protein from both Gram-negative and Gram-positive bacteria. The BugBuster® and rLysozyme™ efficiently lyse the bacterial cells while the Benzonase® degrades nucleic acids to facilitate downstream processing. Requires 5 ml BugBuster and 10 µl Lysonase per 1 g cell paste. The kits provide sufficient reagents for protein extraction from 20 g or 100 g cell paste.

The Column-PROTEIN-Concentrate™ Kit has been specifically developed for concentration of those proteins that cannot be concentrated either by precipitation or other techniques. The kit is based on a proprietary Protein Binding Resin that binds and immobilises any protein in a low salt buffer between pH 2 to 12. The binding capacity is ~0,5 mg protein/ml Protein Binding Resin.

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 (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

UPPA PROTEIN-Concentrate™ Kit uses a proprietary reagent UPPA™ (Universal Protein Precipitation Agent) to quantitatively concentrate dilute protein samples as low as 1 ng/ml. Concentration is not affected by the presence of common laboratory agents, including detergents and chaotropes. After precipitation, the sample is washed to remove salts and other interfering agents; complete recovery of sample is produced.

Supplier: BRUKER DALTRONIK

Tryptic digest of bovine serum albumin, for 5×250 spots

Supplier: Merck Millipore (Calbiochem‎)

Native endoproteinase Lys-C from Lysobacter enzymogenes. Serine protease that specifically hydrolyses amide and peptide ester bonds at the carboxylic side of lysine in peptides and proteins. Designed for protein sequencing or sequence verification, analysis of protein structural domains, and cleavage of fusion proteins. 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

The OrgoSol-PROTEIN-Concentration™ Kit precipitates protein with a proprietary solvent buffer, OrgoSol™. The OrgoSol™ buffer has been specifically developed for efficient precipitation of protein solutions with minimal disruption to the protein structure and therefore maintains the biological activity of most proteins.
