一般說明

Lot specific orders are not able to be placed through the web. Contact your local sales rep for more details. Cells are dissolved in RNAlater for subsequent RNA, DNA, or protein analysis. Note that cell pellets cannot be revived.

PromoCell Cell Pellets are stored in RNAlater® - an aqueous protection solution that rapidly permeates the cells and stabilizes cellular DNA, RNA, and proteins and protects them from degradation. This makes the PromoCell Cell Pellets very useful for a wide range of research applications like gene expression analysis, cell characterization studies, and protein characterization experiments.

Note: RNAlater® denatures proteins. Therefore, proteins will be suitable for e.g. Western blotting but not for applications that require native proteins. Because of the density of RNAlater® Solution, greater centrifugal forces are required to pellet cells. We recommend to transfer the content of the vial into a 15 ml conical tube, to add an equal volume of PBS and to spin down the cells at 5000 x g for 10 minutes at 4°C. Each Cell Pellet is made from 1 million cells and is dissolved in 200 µl RNAlater®. The Cell Pellets are produced from released cell lots and have the same characteristics, i.e. expression profile or cell type specific antigens. On request, viable cells from the same lot are available for cultivation.

應用

Primary Normal Human Epidermal Melanocytes (NHEM) are isolated from the epidermis of juvenile foreskin and are provided in a proliferating format. Melanocytes 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 M3 are isolated using the serum-free, BPE-free and PMA-free Melanocyte Growth Medium M3. Since PMA is a tumor promoting mitogen, it can interfere with experimental approaches. Therefore, we recommend using cells isolated in Melanocyte Growth Medium M3 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.

品質

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).
