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.

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. 

TWEEN-40 is a class of emulsifiers used in some pharmaceutical and food preparations. It is often used in cosmetics to solubilize essential oils into water-based products. Polysorbates are oily liquid derived from PEGylated sorbitan (a derivative of sorbitol) esterified with fatty acids.

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.

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.

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.

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

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

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.

A routine use of agarose is ideal for daily analysis of nucleic acids by gel electrophoresis or blotting (Northern or Southern) and is also suitable for protein applications such as Ouchterlony and radial immunodiffusion (RID). It has low ethidium bromide and SYBR Green background staining.

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

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

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.

Multiplex amplification of 17 loci in a single reaction

Complete profile even from a small amount of DNA
