Purification of Protein A-Tagged Proteins
This page shows how to purify protein A-tagged proteins using Cytiva products.
Antifoams
Antifoams are supplied as two basic types of composition or mixtures of the two. Organic antifoams are of synthetic origin. Silicone-based antifoams are generally considered to be siloxane polymers and are also synthetic.
Media for Staphylococcus Aureus Detection
Chromogenic media enable the selective detection of S. aureus, which produce bluish-green colonies that are clearly differentiated from other species.
Navigating Natural Flavor Regulations
No major regulatory agency in the world that oversees food labeling defines natural ingredients in food, with the exception of natural flavors. The US FDA, European Food Safety Authority (EFSA), Japanese Ministry of Health, and other regions have clear...
Differentiation and Identification Media for Salmonella
Salmonella contamination is the second leading cause of food-borne illness worldwide. Controlling outbreaks of Salmonella is an important task for food regulators, restaurants and the food industry in general. The Salmonella family includes over 2,300 serotypes of bacteria, but two types...

Lactobacilli
Information about lactobacilli, rod-shaped, Gram-positive, fermentative, facultative anaerobic or microaerophilic organotrophs. The lactobacillus organtroph belongs to the lactic acid bacteria group.
Clostridia Diagnostic
Clostridia are relatively large, gram-positive, rod-shaped bacteria that can undergo only anaerobic metabolism.
Determination of Organic Acids in Wine and Fruit Juices with Ion Exclusion Chromatography
The measurement of organic acids in wines is complementary to sensorial and microbiological quality assessment in fermentation control, for example, because the types and concentrations of the different acids influence the resulting color and taste of the wine.
Probiotics and Human Health
Today, diverse studies report the benefits of probiotics, such as inhibitory effects on pathogens, aid in the management or prevention of chronic intestinal inflammatory diseases or atopic syndromes, and support to the immune system. Potential beneficial applications abound, researchers continue...
Yeast
Yeast is one of the most important microorganisms known and utilised by mankind. Ancient Middle Eastern civilisations used the organism to bake bread and to produce mead, beer and wine.
Vibrio Detection
Vibrios are motile, curved or comma-shaped bacilli and have a single polar flagella with sheet proteins. They are often found in open water, freshwater and saltwater.
Recent Advances in Biotechnology and the Impact on Flavors
Over 30,000 years ago hunter-gathers in Asia began domesticating wolves beginning an intentional breeding program resulting in the over 340 recognized dog breeds we have today.
Microbiology in Plant Peptones
Plant peptones for microbial media are a good alternative to animal protein sources. 100% vegetable protein source means no BSE/TSE and no regulatory or compliance concerns.
