The use of sample buffer ensures optimal band resolution when preparing proteins for SDS-PAGE with Tris-glycine-SDS running buffer.Role of reagents: Tris-HCl: as a buffering substance. 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.Color and Shape:Liquid, Dark Blue, ClearBiolit SpryBlue Stain for SDS Page
SpryBlue stain is a staining solution used for staining SDS Polyacrylamide gels. It is a ready-to-use stain for proteins that is quick and sensitive. Based on Coomassie blue G-250 dye’s properties, the stain is more sensitive than Coomassie blue R-250. The added advantage is that it requires no destaining procedures.
Quick staining procedure
- Bands are seen with good intensity within one hour.
- Faint bands seen within 15 minutes of addition of the stain
- No destaining procedures, thus reducing time and effort
- No shrinkage of gels, no background from overnight staining.
- Optional wash with water helps increase sensitivity of fainter bands.Color and Shape:Liquid, BlueSDS PAGE Sample Buffer (2X) (Reducing) (Laemmli Buffer 2X)

CAS:5-Chloro-2-methyl-3-isothiazolone (CMIT) is a highly water-soluble apoptotic agent and preservative with numerous applications. It is used in anti-microbial coatings, latex formulations, hydraulic fracturing fluids, pesticides and cosmetics. CMIT in conjunction with 2-methyl-4-isothiazolin-3-one (MIT) is marketed as Kathon. CMIT is also an allergen. CMIT is active against gram-positive and gram-negative bacteria, yeasts and fungi. CMIT is believed to form mixed disulfides with protein thiol groups which then undergo thiol-disulfide exchange reactions to give mixed protein thiol disulfides leading to cell apoptosis and necrosis.

CAS:Mordant Black 11 is a water-soluble dye that is used in the treatment of wastewater. Mordant Black 11 binds to surface particles and enhances the removal of organic matter from wastewater. It has been shown to be effective for the treatment of human serum, which contains high levels of proteins and other macromolecules. Mordant Black 11 efficiently adsorbs onto the surface of these macromolecules, leading to a decrease in the amount of protein adsorbed on the surface. The kinetic data for this process have been obtained by electrochemical impedance spectroscopy (EIS) and by measuring changes in pH due to ionization. A magnesium salt is required for the synthesis of Mordant Black 11, as well as potassium dichromate or other chromium salts and fatty acids.Formula:C20H12N3NaO7SPurity:Min. 95%Molecular weight:461.38 g/molResazurin
