For selective isolation and culture of Staphylococcus aureus.
Peptone and beef extract powder provides carbon, nitrogen, vitamins and minerals; D- mannitol to fermentable sugars; higher levels of sodium chloride to provide a higher osmotic pressure, suppress most non-staphylococcal microorganisms ; phenolsulfonphthalein as pH indicator; agar is medium coagulant. Typical pathogenic staphylococci (coagulase positive) D- mannitol produce acid fermentation and produce yellow colonies with a yellow halo, typically non-pathogenic Staphylococcus unfermented D- mannitol to form red colonies.

ProbeSure Multiplex Master Mix is an enhanced version of ProbeSure Master Mix, formulated to enable users to analyse up to four targets in one reaction well. For example, two bi-allelic SNPs or one reference gene and a further three genes of interest.
Users will require a plate reader capable of reading FAM, HEX, ATTO 550, ATTO 647N and ATTO 633 (the wavelengths of each of these can be found in our ProbeSure Multiplex Master Mix User Guide). ProbeSure Multiplex Master Mix is supplied at 2x concentration for convenience and is supplied with the ATTO 633 normalising dye at either high level (500 nM final concentration), low level (25 nM final concentration) or without ATTO 633.
