1xTris-EDTA Buffer

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

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.

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.

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.

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.

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.

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

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.

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.

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. 

Super-DI^TM Formamid jest zalecanym buforem obciążającym dla wszystkich sekwenatorów ABI.

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