A computer simulation of the isolated giant axon of the squid to investigate the biophysical properties of nerve. Describes the preparation, apparatus used to record the resting potential of the axon and the...
Demonstrates some classic physics experiments relating to the properties of electrons, showing that electrons travel in straight lines and carry momentum when they interact with objects. J J Thompson, the...
RNA can be difficult to isolate because of the ubiquitous presence of degrading enzymes. Here, whole cells are treated with guanidinium salt to rapidly deproteinise the RNA and denature ribonucleases that...
Lambda bacteriophage are used to clone large fragments of DNA. Here, phage are isolated by first infecting a liquid suspension of bacteria. During incubation the bacteria are lysed by the phage. The phage...
Bacterial plasmids are used to clone DNA. Here, large amounts of bacteria are cultured containing the plasmid. The numbers of plasmids in the bacteria are then amplified by the addition of chloramphenicol....
Standard laboratory procedures. Covers the technique of volumetric analysis: 1) standardisation of sodium hydroxide solution; 2) standardisation of potassium manganate VII solution.
Simulates a number of experiments which can be performed on the heart of a pithed frog to illustrate some important characteristics of heart function. As such it provides a cheap, practical alternative to...
Tissue culture techniques are valuable on humanitarian grounds in that they can greatly reduce the use of laboratory animals. In certain cases they are also attractive for reasons of reduced cost or greater...
Simulates a number of simple experiments which can be performed to illustrate the physiological properties of skeletal muscle and neuromuscular transmissions and is modelled on the frog sciatic...
A computer simulation of experiments which can be performed on the frog sciatic nerve to illustrate the important properties of nerves. The program provides an alternative to the use of live animals in...
