7M Guanidine HCl Solution

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-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.

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.

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.

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

TRITON X-114 is used in biochemical applications to solubilize and separate proteins due to its low cloud point (23 °C).

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

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.

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.

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.

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.

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.

D-(+)-Glucose is a common natural sugar involved in processes such as energy production, glycosylation, and formation of glycans that provide structure to cells. Glucose is involved in a detrimental process in cells called glycation. Glucose is used as a supplement for cell culture and in numerous cellular processes and molecular biology applications.

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.

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.

MCLAB's RNA Storage Buffer, with optimized reagents and pH value, provides better preservation and greater RNA stability for valuable RNA samples than the standard EDTA and TE Buffer or just water.
