Applicazioni

Primary Normal Human Epidermal Melanocytes (NHEM) are isolated from the epidermis of juvenile foreskin. E177Melanocytes are located in the stratum basale, but branch out between the keratinocytes in suprabasal layers. About 5-10 % of the cells in the epidermis are melanocytes. The main purpose of melanocytes is the production of melanin, the protein responsible for the pigmentation of the skin, eyes, and hair. Melanin protects the cells in the skin and in deeper layers from the hazardous effects of UV radiation. It is produced and stored in melanosomes, which are located close to the melanocyte membrane, but it can also be transferred to neighboring keratinocytes.Normal Human Epidermal Melanocytes are isolated using the serum-free, PMA (Phorbol Myristate Acetate)-containing Melanocyte Growth Medium. Since PMA is a tumor promoting mitogen, it can interfere with experimental approaches. Therefore, we recommend using cells isolated in Melanocyte Growth Medium M2 and also using this medium for cultivation. Normal Human Epidermal Keratinocytes (NHEK) and Normal Human Dermal Fibroblasts (NHDF) from the same donor are available on request.

Componenti

PMA-containing Melanocyte Growth Medium

Qualità

Rigid quality control tests are performed for each lot of the corresponding cells. They are tested for cell viability, cell morphology, growth performance and for cell-type specific markers. In addition, all cells have been tested for the absence of HIV-1, HIV-2, HBV, HCV, HTLV-1, HTLV-2 and microbial contaminants (fungi, bacteria, and mycoplasma).

Attenzione

Although tested negative for HIV-1, HIV-2, HBV, HCV, HTLV-1 and HTLV-2, the cells – like all products of human origin – should be handled as potentially infectious. No test procedure can completely guarantee the absence of infectious agents.

Stato fisico

Pellet is dissolved in RNAlater® for downstream analysis of DNA, RNA or protein profiles. Cells are not revivable.
