IL-7 is a hematopoietic growth factor that stimulates T-lymphocyte differentiation and maintains homeostasis of naive T-cells and memory T-cells. It is possible that human IL-7 is involved in the regulation of postnatal development of B-lymphocytes. IL-7 plays an important role in the development of secondary lymphoid organs.

Tubes without fillers are used for the study of blood serum in biochemical, immunological and serological tests. Material for research............... blood serum Scope of application............................ blood serum research in biochemistry, immunology, serology Centrifugation................................ 1000 - 1500 g - 10 minutes

It is intended for taking micro-samples of blood serum and other biological fluids, storing them and transporting them to a medical institution. The Eppendorf tube is a graduated microcentrifuge tube with a snap-on lid. The test tube is made of polypropylene, which provides the possibility of autoclaving in standard mode. It has a frosted window for recording information. The relative centrifugal acceleration is 3000 g.

Test tubes are used for blood sampling in biochemistry and immunology. During centrifugation, the gel forms a strong barrier for 48 hours between the clot and the serum. The gel tubes must be centrifuged no later than 2 hours after blood collection. Material for research............... blood serum Scope of application............................ serum research in biochemistry, immunology Centrifugation.............................. 1500-2000 g - 10 minutes

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 potassium salt of ethylenediaminetetraacetic acid (EDTA) is the preferred anticoagulant for hematological studies. Material for research............... EDTA-blood, plasma Scope of application............................ hematological examination of whole blood

Test tubes are used to count blood cells and study plasma parameters. When mixed with the collected material, heparin blocks the activity of thrombin and inhibits the transition of soluble fibrinogen to insoluble fibrin, inactivating the coagulation factors irreversibly. Material for research............... heparinized blood, plasma Scope of application............................ immunology, hematology Centrifugation................................ 1000 - 1500 g - 10 minutes

The walls of the tubes are covered with a dry clot formation activator to accelerate blood clotting. Mixing blood with it does not affect the result of tests. The acceleration of the blood clotting process significantly reduces the preparation time of the biological sample. Material for research............... blood serum Scope of application............................ blood serum research in biochemistry, immunology Centrifugation................................ 1000 - 1500 g - 10 minutes

The test tubes contain a buffer solution of sodium citrate, which is an anticoagulant. The ratio of citrate to the amount of blood taken is 1:9. Material for research............... citrate plasma, blood Scope of application............................ coagulation study Centrifugation................................ 2000 - 2500 g - 10-15 minutes
