Immortalization Method Spontaneous immortalization
Description The Immortalized Human Epidermal Keratinocytes (SIK) were derived from a sample of human foreskin and the serial cultivation of keratinocytes led to its spontaneous immortalization. The immortalized cells resemble normal human epidermal colonies but with dramatically increased levels of cell cycle regulatory proteins such as cyclin A. Treatment of the Immortalized Human Epidermal Keratinocytes (SIK) with either TGF-f or TPA were highly effective in preventing growth in low calcium medium which is similar to normal keratinocytes. Telomerase activity in the immortalized cells is stimulated approximately 5-fold by cultivation in the presence of epidermal growth factor (EGF). The Immortalized Human Epidermal Keratinocytes (SIK) is useful in studies focusing on dermatology particularly in skin carcinogenesis as telomerase activation in human skin has been found to be associated with exposure to ultraviolet radiation.

Propagation Use of PriCoat™ T25 Flasks (G299) or Applied Cell Extracellular Matrix (G422) is required for cell adhesion to the culture vessels. Grow cells in ECM-coated culture vessels with the following conditions. The base medium for this cell line is PriGrow IV medium available from abm (TM004). To make the completed growth medium, add the following components to the base medium: Fetal Bovine Serum (TM999) to final concentration of 5% and 1% Penicillin/Streptomycin (G255). Atmosphere: air: 95%, CO₂: 5%; Temperature: 37.0°C.
Quality Control 1) Chromosomal analysis; 2) Immunoblotting of cell cycle control proteins; 3) Telomerase activity using telomeric repeat amplification protocol
Disclaimer 1. The CoA for this product (provided upon request) verifies the cell-type specific gene expression via RT-PCR only. All test parameters provided in the CoA are conducted using abm's standardized culture system and procedures. The stated values may vary under the end-user's culture conditions. Please verify that the product is suitable for your studies by referencing published papers or ordering RNA (0.5 μg, Cat.# C207, $450.00) or cell lysate (100 μg, Cat.# C206, $600.00) to perform preliminary experiments, or alternatively use our Gene Expression Assay Service (Cat# C138). All sales are final.
2. We strongly recommend live cell shipments for ease of cell transfer and this option can be requested at the time of ordering. Please note that the end-user will need to evaluate the feasibility of live cell shipment by taking into account the final destination's temperature variation and its geographical location. In addition, we thoroughly test our cell lines for freeze-thaw recovery. If frozen cells were received and not recovered in your lab under the exact, specified conditions (using recommended culture vessel, media, additional supplements, and atmospheric conditions), a live cell replacement is possible at a cost (plus shipping).
