2218720-3	1990	We now show that mouse Ltk- fibroblasts internalize greater than 90% of radioactively labeled, calcium phosphate-precipitated DNA by a temperature- and energy-dependent process but a small pool of 2-3% of radioactively labeled DNA may be internalized even at 4 degrees C or under energy depletion conditions.	calcium phosphate	95-112	leukocyte tyrosine kinase	Mus musculus	23-26	
3126553-2	1988	The frequency of transfection for XUM1 cells after exposure to calcium phosphate-coprecipitated pSV2neo DNA was more than 10(4)-fold less effective than that for Ltk-aprt- (LTA) cells.	calcium phosphate	63-80	leukocyte tyrosine kinase	Mus musculus	162-165	
3990689-2	1985	A family of plasmids with insertion and deletion mutations in the coding region of the herpes simplex type 1 thymidine kinase (tk) gene served as substrates for DNA-mediated gene transfer into mouse Ltk- cells by the calcium phosphate technique.	calcium phosphate	217-234	leukocyte tyrosine kinase	Mus musculus	199-202	
14582156-1	1982	Recombinant phage particles carrying the thymidine kinase (TK) gene of herpes simplex virus type 1, coprecipitated with calcium phosphate, efficiently transformed mouse Ltk- cells to the TK+ phenotype.	calcium phosphate	120-137	leukocyte tyrosine kinase	Mus musculus	169-172
