Product Code: LAB215
A modification of the original Columbia Agar base formulation, Columbia II Agar Base provides a medium that is suitable for use with both defibrinated horse and sheep blood.
The peptone mixture provides a source of nitrogen, essential vitamins and amino acids. The starch provides a carbon source and sodium chloride maintains osmotic balance. Originally described as a general purpose nutritious agar base by Ellner et al. Columbia Agar is more frequently used when enriched by the addition of sterile blood. The medium is suitable for supporting the growth and determining haemolytic reactions of a variety of microorganisms including the majority of clinically significant pathogens.
