For many decades, mammalian cells have been an indispensable part of cell biology and are cultivated in 2D cell cultures, but no in vivo-like conditions could be created with them. The organism is a three-dimensional system and therefore the 3D cell culture comes closest to it.

ANA's are primary markers of a variety of systemic autoimmune diseases. The IFT on HEp2 cells is a "golden standard" screening method. The "Dense Fine Speckled" pattern (DSF70) is often seen on the ANA screen and has no known association with autoimmune diseases. The distinction of disease-associated reactions to standard ANA screening methods can be particularly difficult.

In Class II microbiological safety cabinets, part of the filtered air is directed downwards in a laminar flow. The extracted room air in the area of the front opening is led upwards below the working area, cleaned by a HEPA filter and returned to the working area. The circulating, sterile air flow ensures product and user protection.

S. aureus is the second most common germ that occurs in positive blood cultures. Coagulase-negative S.aureus (KNS) is the most common cause of circulatory infection (about 42%) and S.aureus (about 16.5%) the second leading cause of infection. Some strains are resistant to β-lactams, e.g. Methicillin, and therefore therapy should be optimized for MRSA and MSSA infections.
