2. Leading Developer and Manufacturer of In Vivo and DNA Transfection Kits, Transfection Reagents and Electroporation Delivery Products Products >Weri-Rb-1 Transfection Reagent (Retinoblastoma Cells) Weri-Rb-1 Cell Line Description and Applications The Weri-Rb-1 cell line originates from the retinoblastoma tissue taken from a 1-year old female Caucasian child. The line was established by R.M. McFall and T.W. Sery in 1974. The Weri-Rb-1 cell line is near diploid with a modal chromosome number of 47. The cell line also has two copies of the x chromosome and the normal chromosomes 3, 10, 13 and 16 are absent. Weri-Rb-1 cells do not form colonies, but the round cells grow in clusters in suspension. Weri-Rb-1 cell line has different applications in cell differentiation, biochemical evaluations and tumor therapeutics in animal models due to the line’s variation in frequency and number of microvilli, lamellipodia and surface blebs.

3. Leading Developer and Manufacturer of In Vivo and DNA Transfection Kits, Transfection Reagents and Electroporation Delivery Products Products >Weri-Rb-1 Transfection Reagent (Retinoblastoma Cells) Weri-Rb-1 Transfection Protocol 1. Plate 10,000 - 15,000 Weri-Rb-1 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 Weri-Rb-1 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 Weri-Rb-1 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 >Weri-Rb-1 Transfection Reagent (Retinoblastoma Cells) Data Figure 1. siRNAs targeting Lamin A/C mRNA or non-silencing control siRNA were transfected into Weri-Rb1 cells following the recommended protocol. At 48 hours post-transfection the cells were analyzed by qRT-PCR for Lamin A/C gene expression levels. 18S rRNA levels were used to normalize the Lamin A/C data. Values are normalized to untreated sample. Data are means ± SD (n=4).
