Kanamycin Sulfate

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.

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.

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

5M solution of betaine in MilliQ H2O. DNase, RNase free.

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.

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.

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

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.

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.

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

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.

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.

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.

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.

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.

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.
