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.
Description
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.
Application
A concentrated, standard phosphate buffer solution.
pH Range: 7.3 - 7.5
Recommended Storage Condition: Room temperature
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.
Ammonium Sulfate. (NH4)2SO4 is an inorganic salt with a number of commercial uses.
25% Triton X-100 is a commonly used detergent in laboratories.
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.
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.
Used to select for ampicillin resistance in mutated and transformed cells.
The Super-DITM Formamide is the recommended sample loading buffer for all ABI sequencers.
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.
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.
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.
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.
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.
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.
5M solution of sodium chloride (NaCl) in high purity dH2O. Solution is 0.2 μm filtered and dispensed into durable, square Nalgene bottles.
Bovine Serum Albumin (BSA) has many uses as a carrier protein and as a stabilizing agent in enzymatic reactions. MCLAB’s Ultrapure BSA is a "non-acetylated" BSA, pure enough to use when the integrity of DNA or RNA is essential. It has been tested for DNase, RNase, endonuclease, protease, peroxidase, and alkaline phosphatase activity, and assayed for fluorescence background.
