Most molecules have a net charge within a pH range of 2 to 10. When the pH is altered, the net charge on molecules can change drastically. In this experiment, a mixture of two chemicals is absorbed onto a solid support ion-exchange column and separated during elution under conditions that influence their net charge.

Supplier: Thermo Fisher Scientific

Thermo Scientific™ Pierce™ Rapid Gold BCA Protein Assay Kit is a two-component, high precision, detergent-compatible assay optimised to measure (at 480 nm) total protein concentration compared to a protein standard curve of known concentrations. The Pierce™ Rapid Gold BCA Protein Assay uses the same copper-chelating technology as the well-known traditional Pierce™ BCA Protein Assay and provides comparable accuracy but with a 5 minute, room temperature incubation and measured at 480 nm. This improvement eliminates the need to wait or expose the samples to elevated temperatures for a fast time to results.

Supplier: G-Biosciences

The Affinity Chromatography kit teaches the basic principle of affinity chromatography utilising highly specific affinity columns. This lab activity involves preparation of a crude protein extract and running affinity exchange chromatography for isolation of a protein.

Supplier: MACHEREY-NAGEL

Photometric test kits for the determination of nitrate in water samples.

Supplier: Thermo Fisher Scientific

The Pierce™ Coomassie (Bradford) Protein Assay Kit is a ready-to-use, stable formulation of the traditional Bradford assay reagent to measure (A595 nm) total protein concentration compared to a protein standard.

Supplier: MACHEREY-NAGEL

Photometric test kits for the determination of ortho phosphate in water samples.

Supplier: Thermo Orion

Orion™ AQUAfast tablet reagents perform colorimetric measurements of common water parameters with convenient, rapidly dissolving tablets.

Supplier: G-Biosciences

This lab activity involves analysis of an enzyme reaction using a specific enzyme substrate and inhibitor. Students study how the rate of enzyme reaction is dependent on substrate concentration and the influence of agents (inhibitors) and conditions that affects the enzyme reaction such as pH and temperature.
