The J774A cell line has a population doubling time of approximately 17 hours. The cells are similar to macrophages and are active antibody dependent phagocytosis processes. Research indicates that the J774A cell line can synthesize a significant amount of lysosome. The cell line also continuously synthesizes Interleukin 1 beta (Il1b). This cell line serves as an excellent transfection host for DNA transfection and has applications for research related to biological responses.

J774A Transfection Protocol 1. Plate 10, ,000 J774A 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 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 J774A cells (from step 2) 7. Incubate cells at 37ºC in a humidified CO 2 incubator 8. Assay for phenotype or target gene expression hours after transfection Optional: Transfection efficiency can be increased by addition of Transfection Enhancer reagent. Add 2 µl of Transfection Enhancer reagent hours after transfection If the viability of J774A cells being transfected is affected at 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   USA Telephone   Fax    Leading Developer and Manufacturer of In Vivo and DNA Transfection Kits, Transfection Reagents and Electroporation Delivery Products Products > J774A Transfection Reagent (Melanoma Cells, TIB-67)

Cyclophilin B silencing efficiency was determined by qRT-PCR in the J774A 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).

DNA plasmid expressing Cyclophilin B or siRNA targeting Cyclophilin B were transfected into J774A 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. Products > J774A Transfection Reagent (Melanoma Cells, TIB-67)
