"Solid Phase Extraction"

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.

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.

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.

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

Supplier: G-Biosciences

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: G-Biosciences

Total Protein Extraction (TPE™) Kit is a universal lysis system for the solubilisation of total proteins from animal, plant, yeast, bacteria, and other biological samples. The kit contains ready to use buffers for extracting total protein from cells and tissues for SDS-PAGE analysis.

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.

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

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.

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.

Supplier: G-Biosciences

The HOOK™ Cell Surface Protein Isolation Kit uses HOOK™ biotin labelling and purification technology in conjunction with Mammalian Cell PE LB™ Lysis Buffer to conveniently label cell surface proteins and isolate them for further analysis, including Western blotting. The Kit is supplied with all the necessary reagents and buffers for convenience and improved reproducibility. The kit is compatible with a wide variety of mammalian cells and can be used to compare treated and untreated cells and differences between different cell lines.

Supplier: Thermo Fisher Scientific

The Mem-PER™ Plus Membrane Protein Extraction Kit enables small-scale solubilisation and enrichment of integral membrane proteins and membrane-associated proteins in a simple reagent-based procedure. It effectively isolates membrane proteins from cultured cells and tissues using a simple benchtop microcentrifuge procedure.
