2. Leading Developer and Manufacturer of In Vivo and DNA Transfection Kits, Transfection Reagents and Electroporation Delivery Products Products > HeLa-S3 Transfection Reagent (Cervical Adenocarcinoma) HeLa-S3 Cell Line Description and Applications The HeLa S3 is named as such because it is the third close that was propagated and isolated from the original well-known HeLa cell line. The “S” in the name is a tribute to Dr. Sabin. The HeLa cell line was derived in 1955 and has been used in a wide array of scientific research since. As a derivative of the HeLa cell line, the two cell lines share many properties. The HeLa S3 cell line is also considered to be an immortal cell line and has also been under scrutiny in the media regarding the controversial issue of patient’ rights.

3. Leading Developer and Manufacturer of In Vivo and DNA Transfection Kits, Transfection Reagents and Electroporation Delivery Products Products > HeLa-S3 Transfection Reagent (Cervical Adenocarcinoma) HeLa-S3 Transfection Protocol 1. Plate 10,000 - 15,000 HeLa-S3 cells per well in 0.5 ml of complete growth medium 12–24 hours prior to transfection 2. Wash with 1xPBS and add 0.5 ml of fresh growth medium 3. Prepare transfection complexes by mixing 40 µl of serum-free medium, 5.5 µl of transfection reagent, and • 750 ng DNA (or mRNA), or • 30 nM - 50 nM of siRNA (or microRNA) *Referred to a final volume including growth medium 4. Incubate transfection complexes at RT for 15 - 30 minutes 5. Optional: Add 2 µl of Complex Condenser. This reagent reduces the size of transfection complex, therefore increasing transfection efficiency; however, it may increase cell toxicity 6. Add prepared transfection complexes to 0.5 ml of complete growth medium with HeLa-S3 cells (from step 2) 7. Incubate cells at 37ºC in a humidified CO2 incubator 8. Assay for phenotype or target gene expression 48 - 72 hours after transfection Optional: Transfection efficiency can be increased by addition of Transfection Enhancer reagent. Add 2 µl of Transfection Enhancer reagent 12-24 hours after transfection If the viability of HeLa-S3 cells being transfected is affected at 16 - 24 hours post-transfection, the level of cytotoxicity can be decreased by changing the growth medium and eliminating redundant exposure of cells to transfectant Altogen Biosystems 848 Rainbow Blvd #823  Las Vegas  NV  89107  USA Telephone 702 349 6103  Fax 702 989-0841  email  techserv@altogen.com

Leading Developer and Manufacturer of In Vivo and DNA Transfection Kits, Transfection Reagents and Electroporation Delivery Products Products > HeLa-S3 Transfection Reagent (Cervical Adenocarcinoma) Data Figure 1. Cyclophilin B silencing efficiency was determined by qRT-PCR in the Hela-S3 cells transfected by Cyclophilin B siRNA or non-silencing siRNA control following the recommended transfection protocol. Cyclophilin mRNA expression levels were measured 48 hours post-transfection. 18S rRNA levels were used to normalize the Cyclophilin B data. Values are normalized to untreated sample. Data are presented as means ± SD (n=6).

Protein expression of Cyclophilin B in HeLa-S3 cells. DNA plasmid expressing Cyclophilin B or siRNA targeting Cyclophilin B were transfected into HeLa-S3 cells following Altogen Biosystems transfection protocol. At 72 hours post-transfection the cells were analyzed by Western Blot for protein expression levels (normalized by total protein, 10 µg of total protein loaded per each well). Untreated cells used as a negative control.
