IL-15 is a pleiotropic cytokine. It is essential for the development, survival, and activation of NK cells. Participates in the induction of cytotoxic effector cells. Acting as an interleukin-2 antagonist, IL-15 contributes to the maintenance of CD8+ T memory cells and the maintenance and survival of CD4+ and CD8+ T lymphocytes. Acts on a number of other cells.

Epidermal growth factor is a polypeptide that stimulates the differentiation and growth of epithelial cells.

Cover plates for analysis by the KATO method are designed to cover a slide with biomaterials. The products are made of hydrophilic cellophane, it helps to avoid evaporation of moisture from the sample. Painting technique: Kato plates: plates of hydrophilic cellophane are immersed in a Kato mixture so that they fit together (3-5 ml of Kato solution per 100 plates). After 24 hours, they are ready for use. The finished plates can be stored in a Kato solution in a well-sealed container at room temperature for 6 months. Production Russia Material Hydrophilic cellophane Packing 500 pieces (5*100) Color Transparent Size 20*40mm

Human Serum Albumin (HSA) is the main human plasma protein and has many physiological properties due to its unique structure.

Provides complete tightness during transportation of biological material. The material of the container is polypropylene, the lid is polyethylene. It has a graduated and frosted window for recording. Non-sterile.

Stem cell factor is a growth factor produced mainly by fibroblasts and endothelial cells. The cytokine SCF plays an important role in the survival and proliferation of hematopoietic cells, melanocytes and germ cells, their migration and differentiation.
