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.

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-1500 SM-B is a specialized table for microscopy. The table top is 70 cm deep with a small cutout made of laminate. It is designed for sitting work: the height from the floor to the countertop is 75 cm (this is the height of a regular office desk). External dimensions of the table (W×D×H): 1500×700×750 mm. A small superstructure allows you to compactly place the necessary drugs and accessories next to the workplace. Its dimensions: (W×D×C): 668×120×200 mm. The table top is made of laminated chipboard. It is relatively moisture-resistant, resistant to short-term exposure to acids, alkalis and organic solvents and is well suited for the placement of devices. There is a small semicircular cutout on the front of the table top, which allows you to work more comfortably with the microscope. The side laminated panels of the table (chipboard 16 mm thick) are edged with a PVC edge 2 mm thick, 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.
