Safety awareness in the chemistry laboratory. Emphasises the need to be continually aware of the potential dangers and illustrates simple precautions that should always be followed. Identifies the main areas...
An important part of cell culture is the ability to cryopreserve or freeze cells as a method of storing them. Shows in an actual experiment the method and principles of cryopreserving cells using DMSO with...
This contains excerpts from the videotapes (601-605) and gives a good representation of the programmes.
Shows how DNA is extracted and purified before being analysed using electrophoresis. Southern blotting and probing of the DNA using a radioactively labelled probe. These techniques form the basis of DNA...
Video microscope images are used to characterise commonly used cells. Cells of different morphologies, shapes, sizes, growth patterns and organelle definitions are seen through a phase contrast microscope....
Shows the proper method for quantifying viable cells using a hemocytometer in an actual experiment. Viable cells are distinguished from unhealthy cells with and without using trypan blue exclusion. Also...
Many commonly used cell lines require a solid matrix on which to grow, such as tissue culture plastics. Once they take up all the space on the surface of the plastic, they need to be removed with...
Agglutination of particles by antibodies is an extremely versatile technique for detecting and quantifying both antigens and antibodies. The video uses graphics to explain the basic process of agglutination...
Concepts in organic chemistry: Ideas in STEREOCHEMISTRY are explained and applied to biological systems. CURLY ARROWS demonstrates how reaction mechanisms are illlustrated in two dimensions. AZO DYES...
