Sie haben gesucht nach: Proteinextraktions-Reagenzien
Efficient cell lysis and maximum protein extraction yields are vital to high-quality recombinant protein purification. The protease inhibitor cocktails are for lysing mammalian cells, buffers that solubilize plasma and intracellular membranes, break weak intermolecular bonds, and solubilize most proteins. Making procedures easier to perform, these protein extraction reagents can also be used to isolate proteins from both the cytoplasmic and nuclear fractions of cultured cells.
Immobilised Papain
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.

Immobilised Trypsin
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.

PopCulture® reagent
Supplier: Merck Millipore (Novagen)
Das PopCulture® Reagenz ist ein auf Reinigungsmittel basiertes Konzentrat zur direkten Beimischung in E. coli-Kulturen, um ohne Zellernte wirksam Proteine extrahieren zu können. Rekombinante Proteine können direkt im Rohextrakt analysiert oder durch Hinzufügen einer Affinitätsmatrix, Auswaschen des gewünschten Proteinkomplexes aus der Matrix (zur Entfernung des verbrauchten Kulturmediums und von Zellverunreinigungen) und Elution des gereinigten Proteins aus der Matrix gereinigt werden. Das Proteinaufreinigungsverfahren mit PopCulture ist ideal zur automatisierten Verarbeitung großer Probenmengen in der Proteomikforschung sowie für jede andere Anwendung, für die eine höhere Geschwindigkeit und praktischere Vorgehensweisen sinnvoll sind.
