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.

GET™ Plasmid DNA Miniprep Kit isolates high quality plasmid DNA from 1 to 5 ml E. coli cultures. The kit utilises an enhanced DNA binding column to produce high yields of plasmid.

Supplier: G-Biosciences

T4 GP32 is a single-stranded DNA binding protein with key role in DNA replication, recombination and repair. T4 GP32 binds cooperatively to single stranded DNA and stimulates cell-free DNA synthesis directed by the T4-encoded DNA polymerase. It improves the efficiency of reverse transcriptase during RT-PCR as well as increases the yield of PCR products.

HOOK™ Biotin-Hydrazide and its long spacer arm equivalent, HOOK™ Biotin-LC-Hydrazide, are carbohydrate reactive reagents. HOOK™ carbohydrate reactive biotin reagents react with oxidised carbohydrate side chains. Some biotin reagents do not bind directly to the protein itself, but instead, conjugate to the carbohydrate residues of glycoproteins. The carbohydrate reactive biotin reagents contain hydrazides (-NH-NH₂) as a reactive group. The hydrazide reactions require carbonyl groups, such as aldehydes and ketones, which are formed by oxidative treatment of the carbohydrates. Hydrazides react spontaneously with carbonyl groups, forming a stable hydrazone bond. These reagents are particularly suitable for labelling and studying glycosylated proteins, such as antibodies and receptors.

These CL (Compatible Lowry) Protein Assay is based on the widely cited protein assay by Lowry et. al. (1951). The CL Protein Assay improves upon the traditional Lowry method to be compatible with common laboratory agents known to interfere with Lowry protein assays such as reducing agents (dithiothreitol (DTT), ß-mercaptoethanol and TCEP), detergents, chelating agents, amines, sugars, strong chaotropic buffers, salts, drugs, antibiotics, cobalt and other common laboratory agents.

PAGE-Optimizer™ is a unique, spin column for the preparation of samples for SDS-PAGE. The columns contain a proprietary separation matrix that removes contaminants such as salts, detergents, cellular agents and other common buffering agents. PAGE-Optimizer™ helps eliminate smeared lanes, distorted and/ or smiling bands and swollen lanes. PAGE-Optimizer™ has also been shown to reveal protein bands previously masked by the above interfering agents.
