Sodium Dodecyl Sulfate (SDS), pure
Item number: 04051.1
SDS is commonly used in the preparation of proteins for electrophoresis in SDS-PAGE. This compound works by disrupting non-covalent bonds in proteins, denaturing them and causing the proteins to lose their natural conformation. The new negative charge is significantly larger than the original charge of that protein....

Thiazolyl blue (MTT) 3-(4,5-Dimethyl-2-thiazolyl)-2...
Item number: 15655.1
MTT, a yellow tetrazole, is reduced to purple formazan in living cells. A solubilization solution (usually either dimethyl sulfoxide, an acidified ethanol solution, or a solution of the detergent sodium dodecyl sulfate in diluted hydrochloric acid) is added to dissolve the insoluble purple formazan product into a...

Tricine, ultra pure
Item number: 22870.1
Tricine is a commonly used electrophoresis buffer and is also used in resuspension of cell pellets. It has a higher negative charge than glycine allowing it to migrate faster. In addition its high ionic strength causes more ion movement and less protein movement. This allows for low molecular weight proteins to be...

Dithiothreitol (DTT)
Item number: 04010.10
DTT is an unusually strong reducing agent, because once oxidized, it forms a stable six-membered ring with an internal disulfide bond. The reduction usually does not stop at the mixed-disulfide species because the second thiol of DTT has a high propensity to close the ring, forming oxidized DTT and leaving behind a...

Glycine, ultra pure
Item number: 04943.1
Glycine (abbreviated as Gly or G) is the smallest of the 20 amino acids commonly found in proteins, having a hydrogen substituent as its side-chain. Its codons are GGU, GGC, GGA, GGG of the genetic code. Glycine is often used as a counterion in SDS-PAGE and in buffers for western blotting.

HEPES, ultra pure
Item number: 05288.1
HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) is a zwitterionic organic chemical buffering agent. It is one of the twenty Good's buffers. HEPES is widely used in cell culture, largely because it is better at maintaining physiological pH despite changes in carbon dioxide concentration (produced by...

MOPS, ultra pure
Item number: 06170.1
MOPS is frequently used as a buffering agent. It is a structural analog to MES. Its chemical structure contains a morpholine ring. With a pKa of 7.20, MOPS is an excellent buffer for many biological systems at near-neutral pH.

Tris, ultra pure
Item number: 08003.1
Tris is widely used as a component of buffer solutions, such as in TAE and TBE buffer, especially for solutions of nucleic acids. It is a primary amine and thus undergoes the reactions associated with typical amines, e.g. condensations with aldehydes.

NAD+, free acid
Item number: 16110.1
Nicotinamide adenine dinucleotide, abbreviated NAD+, is a coenzyme found in all living cells. The compound is a dinucleotide, since it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine base and the other nicotinamide.In metabolism, NAD+ is involved in redox...
