Vascular Endothelial Growth Factor is one of the key regulators of angiogenesis. The most important role in the human body is played by a protein of the VEGF family called VEGF-A. VEGF-A is a 45 kDa glycoprotein homodimer and plays a key role in chemotaxis and angioblast differentiation, endotheliocyte (EC) proliferation, vasculogenesis, and vascular remodeling. As a result of alternative splicing or proteolytic cleavage, 4 main isoforms of VEGF-A are formed, consisting of 121, 165, 189, or 206 amino acid residues.

The NV-800 SCb is a large specialized laboratory table with a damping concrete slab on a sand cushion. It is designed to accommodate centrifuges, sieves and other devices that vibrate strongly during operation. Dimensions when assembled: 860×860×750 mm. The table has a reinforced metal frame. The main countertop has a built-in drawer open from above, which contains a sand cushion. It is closed with a heavy concrete slab, which is attached to a second, smaller countertop. The sand cushion and the concrete base of the second countertop provide good protection against vibrations. The size of the anti-vibration countertop: 660×660 mm. Like the main countertop, it is made of chipboard, and visually they do not differ from each other. The table has a metal frame painted with white powder paint. The side laminated panels (chipboard with a thickness of 16 mm) are edged with a durable PVC edge with a thickness of 2 mm, which increases their impact resistance and mechanical strength. The legs of the table are adjustable in height within two centimeters, allowing you to place it even on a rather uneven floor.

The FGH-1-2 chromatographs have retained the main advantages of the FGH-1 model – mobility and ease of operation and maintenance. At the same time, FGH-1-2 has all the advantages of a modern multichannel chromatograph – the ability to reliably identify and accurately determine the concentrations of various pollutants of environmental objects. The additional use of automatic identification in the processing of chromatograms simultaneously through both channels makes FGH-1-2, in fact, a universal selective gas analyzer of organic substances using the chromatographic separation method. In FGH-1-2, as well as in FGH-1, all methodological problems have been solved: all measurement methods (MI) used are certified, the devices are equipped with sampling devices prescribed in MI, the devices are graded according to the required substances, independent control of the stability of calibration characteristics and measurement errors is provided.
