Molecular Grade Water is ultrapure water that certified RNase, DNase and Protease free, is suitable for use in molecular biology applications, which demand a high quality of water and assurance that the water is free from nucleases and protease contamination. No toxic agents, such as DEPC, are used in the manufacturing of Molecular Grade Water, eliminating DEPC interference of enzymatic reactions.

Supplier: G-Biosciences

Laboratory reagent grade, sterile distilled water for your laboratory needs. This water is purified by steam distillation and sterile filtered for use as a research laboratory reagent. The distilled water is low endotoxin <0.025EU/ml and low conductivity (<10uS). This water is ideal for the preparation of reagents, rinsing of glassware and plasticware, and various other laboratory and research applications. No toxic agents such as DEPC are included in the preparation of distilled water, eliminating interference with enzymatic analysis.

The Gram staining method was first described in 1844 by the Danish bacteriologist Hans Christian Gram, after whom the test was named. The Gram staining test for bacteria is one of the most important tests in microbiology and is often one of the first tests performed in the identification of bacteria. The Gram staining method utilises the properties of bacterial cell walls and the stain crystal violet. Gram-positive microorganisms have a higher peptidoglycan and lower lipid content than Gram-negative bacteria in their cell walls and this makes them capable of retaining the Gram stain. This kit is supplied with two strains of bacteria and all the necessary components to carry out the Gram staining.

EndotoxinOUT™ consists of 6% cross-linked agarose covalently linked to polymyxin B to bind and remove harmful pyrogens from a solution.

Supplier: G-Biosciences

Immobilised Iminobiotin Resin consists of iminobiotin, a cyclic guanido analog of biotin, covalently coupled to 6% crosslinked agarose. The resin allows for the purification of avidin, streptavidin and Neutravidin and their subsequent gentle elution using non denaturing elution buffers.

Supplier: G-Biosciences

Streptavidin Resin is designed for the single step small and large scale affinity purification of proteins and antibodies with a biotin tag. Biotin, a 244 Da vitamin (Vitamin H) molecule, exhibits an extraordinary binding affinity for avidin (Ka=10¹⁵ M⁻¹) and streptavidin (Ka=10¹⁵ M⁻¹). Biotin and (strept)avidin interaction is rapid and once the bond is established it can survive up to 3M guanidinehydrochloride and extremes of pH. Biotin-avidin bonds can only be reversed by denaturing the avidin protein molecule with 8M guanidine-hydrochloride at pH 1,5 or by autoclaving. The biotinylated molecules are efficiently probed with avidin or streptavidin conjugated to reporter molecules, such as peroxidases or phosphatases.

The physical properties of proteins kit is a lab activity that enables students to investigate the physical properties of several different proteins. Students will learn about protein solubility and how it is affected by various parameters; including temperature, pH, salt and dielectric constant. They will understand about protein precipitation due to pH, high salt and in the presence of organic solvents and about protein denaturation as a result of high temperature. In addition, the kit will demonstrate how non-protein agents, such as detergents drastically alter the physical properties of protein molecules and as a result, understand the importance of detergents in protein solubilisation. This lab activity involves analysis of three different types of pure proteins and then students alter some of those properties with a detergent and re-examine physical properties of those proteins. Students are challenged to consider how physical properties of protein molecules can be exploited for purification and characterisation of proteins and apply their findings on a test sample of complex tissue extract.
