Product news

Microbiological contamination is a well recognized problem of research reagents in many applications. Especially elevated endotoxin levels often lead to misinterpretations in cell culture or animal model experiments. Today, Profos AG, Regensburg is pleased to announce the imminent launch of EndoGrade™ Ovalbumin.

With the first of the globally unique EndoGrade™ products – with lowest endotoxin content – Profos sets new quality guidelines for reagents in immunology and cell culture.

The glycoprotein ovalbumin is the main constituent in egg white. Currently ovalbumin is one of the extensively used proteins in animal studies and also an established model allergen for airway hyper-responsiveness (AHR). Using its proprietary technology EndoTrap® Profos AG established an efficient endotoxin removal process to provide ovalbumin with lowest endotoxin content. The product is designed to give researchers the ability to ensure accurate results by avoiding side effects by endotoxin stimulation.

With EndoGrade™ Ovalbumin Profos takes another step to become a global market leader in the field of endotoxin removal systems and high-quality endotoxin-free products. Further products are in development and will expand the growing portfolio continuously.

Cell / Tissue CultureCell culture or tissue culture is used to study the biology of cells or tissues and to isolate cellular products in an environment which can be manipulated and well defined. Accurately control your culture environment with bioreactors or culture incubators, bind your cells to a surface or together with an extracellular matrix. Distinguish cell types with differential media or proliferate cells with certain characteristics using selective media. Enrich your media with supplements such as growth factors, sera and vitamins. Find the best cell and tissue culture products, kits and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.

Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.Cell-Based AssaysCell-based assays are used to monitor the presence, quantity and activities of a desired cellular analyte including drug molecules or biomarkers. This can reveal information on cell health (apoptosis, cytotoxicity, viability and proliferation assays), cell metabolism, cell migration and cell signaling mechanisms.
