DEPC-Treated Water

TRITON X-114 is used in biochemical applications to solubilize and separate proteins due to its low cloud point (23 °C).

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.

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.

Sodium hydroxide is commonly used in the clandestine production of methamphetamine to change the pH of the solution to a basic pH so that it can become soluble in an organic solution.

MCLAB’s 7M Guanidine-HCl Solution is a ready-to-use solution of guanidine hydrochloride, which can be easily diluted and pH-adjusted to any concentration below 7M.

HEPES Solution is a biological buffer useful in cell culture media. Selection of suitable nutrient medium is dependent on type of cell, conditions of culture, and degree of chemical definition required for the cell culture application.

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 acetate is a widely used reagent in molecular biology and chromatography. Suitable applications include the purification and precipitation of DNA and protein crystallization. Ammonium acetate is commonly used in HPLC and MS analysis of various compounds, such as oligosaccharides, proteins, and peptides.

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. 

Phosphate-buffered saline (PBS) is a balanced salt solution that is used for a variety of cell culture applications, such as washing cells before dissociation, transporting cells or tissue samples, diluting cells for counting, and preparing reagents. PBS is formulated without calcium and magnesium for rinsing chelators from the culture before cell dissociation.

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.

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

Kanamycin Sulfate solution is an aminoglycoside antibiotic consisting of a six-membered aminocyclitol ring attached to aminosugar side chains through glycosidic bonds. Kanamycin Sulfate solution acts by inhibiting protein synthesis, and compromising translational fidelity in susceptible bacteria.

Buffer EB is the elution buffer used in many Qiagen kits, e.g. PCR, Gel Extraction, Nucleotide Removal Kits, MinElute Kits  and the QIAprep Miniprep Kits for DNA cleanup or small-scale plasmid purification. The purified DNA can also be eluted in TE (10 mM Tris-Cl, 1 mM EDTA, pH 8.0), but the EDTA may inhibit certain subsequent enzymatic reactions.

MCLAB's high-purity 30% acrylamide/bis-acrylamide solution is a safer alternative to handling powdered acrylamide.

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.
