Ammonium Acetate

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

CHAPSO (3-[(3-cholamidopropyl)dimethylammonio]-2-hydroxy-1-propanesulfonate) is a zwitterionic detergent used to solubilize proteins. Due to its low light absorbance in the ultraviolet region of the electromagnetic spectrum, CHAPSO is useful for researchers monitoring ongoing chemical reactions or protein-protein binding with UV/Vis spectroscopy.

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.

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.

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.

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

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. 

Linear acrylamide is widely used as one of the coprecipitants which are inert substances used to aid recovery of nucleic acids before alcohol precipitations.

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.

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

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.

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.

Brij-35 (30% Solution) is a nonionic polyoxyethylene surfactant that is most frequently used as a component of cell lysis buffers or as a surfactant in various HPLC applications.

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.

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

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.
