Décrite pour la première fois en 1844 par le bactériologiste danois Hans Christian Gram, la méthode de coloration de Gram porte le nom de son inventeur. La coloration des bactéries de Gram constitue l'un des principaux tests en microbiologie et souvent l'un des premiers tests pratiqués dans l'identification des bactéries. La méthode de coloration de Gram fait appel aux propriétés des parois des cellules bactériennes et au colorant cristal violet. Les parois des microorganismes à Gram positif ont une plus grande quantité de peptidoglycanes et une teneur lipidique inférieure aux bactéries à Gram négatif, ce qui leur permet de retenir le colorant de Gram. Ce kit est fourni avec deux souches de bactéries et tous les composants nécessaires pour réaliser la coloration de Gram.

Pour les biologistes moléculaires et les manipulateurs généticiens, l'une des principales difficultés consiste à détecter et à analyser facilement les mutations génétiques qui se produisent naturellement et provoquent des maladies, ou dans le cadre de manipulations génétiques ou de clonages, délibérés ou accidentels. Les étudiants se forment aux différents types de mutations génétiques, notamment substitutions, délétions et mutations ponctuelles, ainsi qu'aux diverses techniques employées pour détecter ces mutations. Le kit contient tous les réactifs pour dépister les échantillons cliniques simulés d'un gène mutant, par PCR et cartographie de la digestion par des enzymes de restriction. Les étudiants réalisent une simple expérience de diagnostic clinique afin d'identifier un patient malade.

Streptavidin Resin is designed for the single step small and large scale affinity purification of proteins and antibodies with a biotin tag. Biotin, a 244 Da vitamin (Vitamin H) molecule, exhibits an extraordinary binding affinity for avidin (Ka=10¹⁵ M⁻¹) and streptavidin (Ka=10¹⁵ M⁻¹). Biotin and (strept)avidin interaction is rapid and once the bond is established it can survive up to 3M guanidinehydrochloride and extremes of pH. Biotin-avidin bonds can only be reversed by denaturing the avidin protein molecule with 8M guanidine-hydrochloride at pH 1,5 or by autoclaving. The biotinylated molecules are efficiently probed with avidin or streptavidin conjugated to reporter molecules, such as peroxidases or phosphatases.
