The Quantitative Precipitin Technique is a simple technique that is routinely used in the analysis of antibody and antigen interactions and for the estimation of the antibody or antigen content...

Immunoprecipitation is a routinely used technique that removes a protein or peptide, which specifically reacts with an antibody, from a solution. The name of the technique is a misnomer as...

A single protein molecule rarely carries out its role in the body on its own. Many proteins and cofactors are often involved and act as regulators, activators or inhibitors of the...

Protein labeling is an important technique that allows researchers to study a protein’s location, movement and interactions within a living cell.  The most common labels used are fluorescent labels that...

Dialysis is a routinely used technique in research laboratories to “change” the solution a biomolecule is dissolved in. Often the buffers used to isolate biomolecules, such as proteins, are not compatible...

Nucleic acids (DNA and RNA) and proteins are routinely resolved by electrophoresis, which separates molecules based on size and/or charge. Following electrophoresis, the molecules need to be extracted from the electrophoresis...

Membranes play a crucial role in cells by enclosing specific compartments and regulating the entry and exit of metabolites and other crucial components in and out of a cell.  They...

A hands on lab activity to study immunoaffinity chromatography and use a specific antibody to purify antigenic proteins from complex samples. This technique involves performing a chromatography procedure using antigen...

Lab activity that teaches the use of lock-key matching properties of antigen-antibody for detection as well as quantification of antibody or antigenic proteins in complex samples. This method is widely...

This lab activity teaches the use of highly specific matching properties of antigen-antibody for detection of antigenic or antibody proteins in complex samples. One such immunodetection method is widely known as...

This lab activity is designed to study highly specific lock-key matching properties of antigen-antibody and how this highly specific interaction can be exploited as a tool for research and analysis....

Zymography is an electrophoretic technique that includes a substrate copolymerised with the polyacrylamide gel for the detection of enzymes and their activity. Samples are prepared without denaturing the active enzymes...
