CRM007 Chromogenic E. coli O157

Introduction

Usage:

For selective isolation and culture of Staphylococcus aureus.

Principle:

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.

Formulation(per liter):
Pancreatic digest of casein 5.0g
Pancreatic digest of animal tissue 5.0g
Beef Extract 1.0g
Sodium Chloride 75.0g
Mannitol 10.0g
Phenol Red 0.025g
Agar 15.0g
Final PH 7.4±0.2

How to use：

Propargyl-PEG4-alcohol is a Click Chemistry reagent that can react with azide-bearing compounds or biomolecules; copper is needed as a catalyst. The PEG units help increase the solubility of the molecule in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-PEG6-amine is a PEG linker which contains DBCO and amine moieties. The DBCO group is commonly used in copper-free Click Chemistry reactions. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydrophilic PEG spacer increases the water solubility of the compound.
