7M Guanidine HCl Solution

The loading dye increases the density of the sample and adds colours to the sample, thereby simplifying the loading process. The solution contains dyes that, in a electric field, move toward the anode at predictable rates.

Ammonium Persulfate (APS) is an oxidizing agent that is used with TEMED to catalyze the polymerization of acrylamide and bisacrylamide to prepare polyacrylamide gels for electrophoresis.

SDS, sodium dodecyl sulfate is an anionic surfactant. SDS is commonly used in laboratory as a component of buffer for cell lysis, cell lysis during DNA extraction, and mostly in SDS-PAGE running buffer. Indeed, SDS is an anionic detergent applied to protein samples to linearize proteins and to impart a negative charge to linearized proteins.

CHAPS (3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate ) is a zwitterionic detergent used to solubilize proteins. It is used as a non-denaturing solvent in the process of protein purification and is especially useful in purifying membrane proteins.

MCLAB's RNA Storage Buffer, with optimized reagents and pH value, provides better preservation and greater RNA stability for valuable RNA samples than the standard EDTA and TE Buffer or just water.

Tris Buffered Saline (TBS) is an isotonic, non-toxic buffer used in some biomedical techniques to maintain pH within a relatively narrow range. TBS can shift pH relatively drastically as temperature changes, with the pKa declining approximately 0.03 units per degree Celsius rise in temperature.

EDTA, 0.5 M, pH 8.0, is a sterile-filtered solution of 0.5 M EDTA in H₂O treated with diethyl pyrocarbonate (DEPC).

TAE buffer is the most commonly used buffer for DNA agarose gel electrophoresis but is also used for non-denaturing RNA agarose gel electrophoresis¹. Double-stranded DNA tends to run faster in TAE than in other buffers but can also become exhausted during extended electrophoresis. 

IPTG (isopropyl-beta-D-thiogalactopyranoside) is a highly stable synthetic analog of lactose. It inactivates the lac repressor and induces synthesis of beta-galactosidase, an enzyme that promotes lactose utilization. IPTG is used to induce expression of cloned genes under the control of the lac operon.

TE Buffer is a common molecular biology buffer used for protection of DNA and RNA from degradation. The Tris buffering agent and EDTA metal chelating properties help to protect DNA and RNA.

Ammonium Sulfate. (NH4)₂SO₄ is an inorganic salt with a number of commercial uses.

The Super-DITM Formamide is the recommended sample loading buffer for all ABI sequencers.

TWEEN 20 helps to prevent non-specific antibody binding in enzyme immunoassay as a washing agent (e.g. Western blots and ELISAs). In this major application, it is dissolved in Tris-Buffered Saline or Phosphate buffered saline at dilutions of 0.05% to 0.5% v/v.

Acetylated BSA is used as a carrier protein and an enzyme stabilizer in which the absence of contaminants such as nucleases and proteases is vital. The acetylation process inactivates any trace of active nuclease activity. While the acetylation process does change BSA's binding characteristics and makes it inhibitory in PCR reactions, it is normally added to restriction digests.

D-(+)-Glucose is a common natural sugar involved in processes such as energy production, glycosylation, and formation of glycans that provide structure to cells. Glucose is involved in a detrimental process in cells called glycation. Glucose is used as a supplement for cell culture and in numerous cellular processes and molecular biology applications.
