CHAPSO

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.

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

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.

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.

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. 

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.

5M solution of sodium chloride (NaCl) in high purity dH₂O. Solution is 0.2 μm filtered and dispensed into durable, square Nalgene bottles.

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.

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.

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.

Contains 100% active components and is a mixture of organic non - silicone polypropylene based polyether dispersions. Can be sterilized repeatedly.

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.

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

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

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.
