SDS PAGE Sample Buffer (5X) (Reducing) w/ DTT w/ BPB
It is the most commonly used sample buffer for SDS-PAGE of denatured proteins. It is a ready-to-use 5X solution with dithiothreitol (DTT) as a reducing agent. It can be used for SDS-PAGE protein loading of conventional proteins. The use of sample buffer ensures optimal band resolution when preparing proteins for SDS-PAGE with Tris-glycine-SDS running buffer. :It is the most commonly used sample buffer for SDS-PAGE of denatured proteins.

The pH play an essential role in preserving peptide bonds from breaking apart. SDS: Proteins comes in different sizes and charges. SDS is an anionic detergent that helps in linearizing (by denaturing) the proteins and bringing a net negative charge to the proteins irrespective of the initial charge. Glycerol: The high density (thickening of the solution) of glycerol ensures the sample moves down into the well. DL-Dithiothreitol (DTT): is a strong reducing agent. Its specific role in sample denaturation is to remove the last bit of tertiary and quaternary structure by reducing disulfide bonds. Bromophenol Blue: visually indicates the location (tracking dye) of the sample in the gel.Couleur et forme :Liquid, Dark Blue, ClearTris(hydroxymethyl)aminomethane [for Electrophoresis]

CAS :Potassium cacodylate is a model system for the study of enzyme-catalyzed reactions. It is a monoclonal antibody that activates the hydroxyl group on cysteine, which can be used to detect time. Potassium cacodylate is an irreversible enzyme and polymerase chain reaction (PCR) substrate. Potassium cacodylate has been used as a diagnostic tool in autoimmune diseases and in necrotic cell death. The tyrosine kinase domain in the protein encoded by this gene is responsible for binding ATP and phosphotyrosine, serving as a docking site for many proteins involved in signal transduction. The acyl chain of potassium cacodylate consists of two fatty acid chains that are linked by an ester bond, with one long-chain fatty acid connected to a short-chain fatty acid via an ester bond or amide bond.Formule :C2H6AsKO2Degré de pureté :Min. 95%Masse moléculaire :176.09 g/molReagecon Buffer Standard pH 5.00 at 20°C ISO 17034 Certified Reference Material

CAS :HEPPS is a drug that belongs to the group of organic compounds with a sulfate group. It is a dextran sulfate salt that is used as an anticoagulant in blood transfusions, as a diagnostic aid for liver diseases, and to treat various types of bacterial infections. HEPPS has been shown to have irreversible inhibition on cytochrome P450 enzymes and thus can be used as an antimicrobial agent. This drug also has coordination geometry, which makes it act as a calcium-binding agent and have p450 activity. HEPPS has been shown to be toxic for the liver and fetal bovine cells.Formule :C9H20N2O4SDegré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :252.33 g/moldi-Sodium hydrogen phosphate, anhydrous
