5M Sodium Chloride

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

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.

Reported use in all phases of detergent compounding and aqueous processing in the textile and paper industries, in industrial metal cleaners, acid cleaners, floor cleaners, detergent sanitizers and waterless hand cleaners.

DEPC-treated Water is deionized, high quality, molecular biology grade water.

The β-galactosidase substrate X-Gal (5-bromo-4-chloro-3-indolyl-β-D-galactopyranoside) is a chromogenic stain for β-gal activity, and is commonly used to distinguish between recombinants and nonrecombinants by lacZ α-complementation with appropriate vectors and hosts.

DEPC-treated Water is deionized, high quality, molecular biology grade water.

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. 

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

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.

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.

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

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.

Used to select for ampicillin resistance in mutated and transformed cells.
