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.

HOOK™ IgG biotinylation kits are designed for the biotinylation of IgG molecules by immobilising the IgG molecules on a solid support. Nickel chelating resin allows for the rapid removal of uncoupled biotin and therefore eliminates the need for further dialysis or desalting of the biotinylated antibody.

Detergents are essential for protein solubility during protein extraction and sample preparation, especially when working with hydrophobic proteins. The presence of high concentrations of detergents in protein samples can impair ELISA, IEF, protease digestion of proteins and suppress peptide ionisation when analysed by mass spectrometry.

This lab activity has two objectives - to deepen the understanding of protein molecules and for students to learn the potential of electrophoresis in protein analysis. Students study the fundamentals of protein structure from their primary structure to the more complex tertiary and quaternary structures, utilising protein electrophoresis. Complex mixtures of protein samples and characterised pure protein samples, in conjunction with electrophoresis, are utilised to study protein structure and the potential of protein electrophoresis. Using non-denaturing and denaturing electrophoresis, students understand the difference between primary, tertiary and quaternary structures, the importance of disulfhydryl bridges in maintaining protein structure and electrophoresis in studying complete proteins and protein subunits.

Ion exchange chromatography is used to separate charged molecules from complex biological samples. The charged molecules bind to a solid support carrying an opposite charge to the molecule. Proteins contain regions of charged groups on the surface which interact with the ion exchange groups immobilised on the solid support (resin column). Immobilised proteins are eluted by changing either pH or the salt gradient or a combination of both. This lab activity involves preparation of a crude protein extract and running ion exchange chromatography for isolation of proteins.

This kit teaches aseptic handling techniques and cultivation of bacteria in liquid culture media and on solid phase agar plates. This kit is designed to educate students about the various stages of the bacterial growth cycle, i.e. lag, log or exponential, stationary and decline or death phases. The kit also teaches the importance of growing bacteria on solid phase agar plates to isolate single colonies of bacteria. This lab activity involves preparation of culture medium and solid agar plates.

In this lab activity, students learn to perform simple protein isolation procedures to isolate the protein fingerprint from various fresh tissues. They will compare the protein fingerprints of four different tissues to understand that the function of a particular organ is due to the proteins that are localised to the specific organ. Also included in this kit are four dried protein samples (from mouse liver, brain, heart and lungs) to compare as a control, if fresh tissues cannot be obtained.

The femtoELISA™ kits utilise a non animal protein blocker, NAP-BLOCKER™ that minimises cross-reactivity with researcher's antigens and antibodies. For the detection of HRP, an improved, ultra sensitive, non volatile, stable colorimetric substrate based on tetramethyl benzidine (TMB) is supplied. Reagent does not require hydrogen peroxide that can have detrimental effects on many biological factors, which may ultimately affect the assays.

Sulpho-NHS reacts primarily with primary amines to convert carboxyl groups to amine reactive sulfo-NHS esters. It is ideal for cross-linking, chemical labelling and solid support immobilisation. It is used to generate amine reactive esters from carboxylate groups and is primarily used to increase the efficiency of the carbodiimide EDC cross-linking. EDC reactions do not require Sulpho-NHS; however, its presence greatly enhances cross-linking efficiency and allows for a two-step process. EDC reacts with a carboxylate group to form an active ester, which is subject to rapid hydrolysis in aqueous buffers. The Sulfo-NHS increases the stability of the active intermediate and the resulting coupled product is identical to EDC reactions without sulpho-NHS.
