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

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.

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

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.

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.

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.

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.

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

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.

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.

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.

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. 

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.

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

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.

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

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.
