5M Sodium Chloride

Brij-35 (30% Solution) is a nonionic polyoxyethylene surfactant that is most frequently used as a component of cell lysis buffers or as a surfactant in various HPLC applications.

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.

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

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.

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.

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.

LB Agar plates contain 1.0% Tryptone, 0.5% yeast extract, 0.5% NaCl, 1.5% agar.

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

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.

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

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

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.

5M solution of betaine in MilliQ H2O. DNase, RNase free.

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.

Low concentration solutions of DNA are prone to DNA degradation or other loss. It is critical that optimal methods are employed for DNA suspension and long-term storage.
