Normal Human Epidermal Melanocytes neonatal

Description: Melanocytes are melanin-producing neural crest-derived cells located in the bottom layer (the stratum basale) of the skin's epidermis, the middle layer of the eye (the uvea), the inner ear, vaginal epithelium, meninges, bones, and heart. Melanocytes represent 5-10% of the cells in the epidermis and are specialized in the production of melanin. This protein is responsible for the pigmentation of the skin, hair and eyes and exerts a protective effect on adjacent cells by shielding them from the harmful effects of UV radiation.
Human Epidermal Melanocytes (HEMs-j) from Creative Bioarray are isolated from the healthy human foreskin tissue. The cells are cryopreserved at Passage 2, with each vial containing at least 0.5 x 10^6 cells. Human Epidermal Melanocytes (HEMs-j) are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HEMs-j are guaranteed for further at least 15 population doublings under the conditions provided by Creative Bioarray. Repeated freezing and thawing of cells is not recommended.

Description: Keratinocytes are the primary type of cell found in the epidermis, the outermost layer of the skin. Keratinocytes represent the major cell type of the epidermis, making up about 90% of the cells. They originate in the stratum basale and undergo gradual differentiation including profound morphological changes during their shift to the stratum corneum. In the stratum corneum, the final barrier layer of the skin, keratinocytes are found as nucleus-free, flat, and highly keratinized squamous cells.
Creative Bioarray provides Human Keratinocytes - juvenile (HKs-j) isolated from the dermis of juvenile foreskin. These cells are cryopreserved at Passage 2 and shipped frozen, with each vial containing at least 0.5 x 10^6 cells. HKs-j are free from HIV-1, HBV, HCV, mycoplasma, bacteria, yeast, and fungi, and are guaranteed for at least 15 population doublings under the conditions provided by Creative Bioarray. Repeated freezing and thawing of cells is not recommended.

Human Keratinocytes - adult (HKs-a) from Creative Bioarray are isolated from the Dermis of adult skin. The cells are cryopreserved at Passage 2 and delivered frozen. Each vial contains at least 0.5 *10^6 cells. HKs-a are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. Human Keratinocytes - adult (HKs-a) are guaranteed to at 15 population doublings under the conditions provided by Creative Bioarray. Repeated freezing and thawing of cells is not recommended.

Human keratinocytes from pooled adult donors at Creative Bioarray are isolated from the dermis and cryopreserved at Passage 2. Each vial contains a minimum of 0.5 x 10^6 cells, which are frozen upon delivery. The cells test negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast, and fungi. Creative Bioarray guarantees at least 15 population doublings under the conditions provided by Creative Bioarray. Repeated freezing and thawing of cells is not recommended.

Description: Creative Bioarray's normal Human Epidermal Keratinocytes (HEK), when grown in Creative Bioarray's LIDer K Medium, provide an ideal serum-free culture model, for the study of wound healing, toxicology or epithelial biology. When in need of multiple keratinocyte cell lots, our HEK, 10-donor pool offers a wide range of donor demographics for research at an economical price. All HEK are quality tested in LIDer K Medium to ensure optimal serum-free growth over a period of at least 15 population doublings at rates equal to or greater than serum-supplemented medium. Our HEK need not be exposed to antimicrobials or phenol red when cultured in LIDer medium; an advantage since these supplements can cause cell stress and "masking effects" that may negatively impact experimental result.

Cell Features:
HEKn are cryopreserved as primary cells. Cells are isolated from neonatal human foreskin and expanded once in culture vessels before cryopreservation.
HEKa are cryopreserved as primary cells. Cells are isolated from adult human skin and expanded once in culture vessels before cryopreservation.
HEK can be grown without serum, phenol red or antimicrobials when cultured in DermaLife medium.
HEK are extensively tested for quality and optimal performance.
Creative Bioarray guarantees performance and quality.

Description: Creative Bioarray's normal Human Epidermal Melanocytes adult (HEMa), when grown in Creative Bioarray's LIDer Ma Medium, provide an ideal low serum culture model, without PMA or Cholera toxin, for the accurate testing of compounds and for use in the study of cancer or dermal biology. Creative Bioarray's HEMa are cryopreserved as secondary cells to ensure the highest viability and plating efficiency. Our HEMa are quality tested in LIDer Ma Medium to ensure optimal reduced-serum growth over a period of at least 15 population doublings at rates greater than media supplemented with higher serum, PMA or Cholera toxin.

Cell Features:
HEM are cryopreserved after primary culture or secondary culture isolated from human skin and expanded once or twice in culture vessels before being harvested for cryopreservation.
HEMn can be grown in a low serum medium without phenol red or antimicrobials when cultured in DermaLife M Medium.
HEMa can be grown in a low serum medium without phenol red or antimicrobials when cultured in DermaLife Ma Medium.
Culture HEM without PMA or cholera toxin or other artificial non-specific stimulants
HEM are extensively tested for quality and optimal performance.
