Example sentences for: serum-free
How can you use “serum-free” in a sentence? Here are some example sentences to help you improve your vocabulary:
The resulting pMIRB-HA-NPM3 plasmids (both sense and antisense orientations) were transiently transfected into NIH 3T3 cells, using transfection conditions with Lipofectamine and OptiMEM serum-free medium (Gibco-BRL, Bethesda, MD) as described [ 49 ] . Following a six-hour incubation of the DNA-Lipofectamine complexes in OptiMEM, the cells were washed and incubated in 10-cm dishes with their usual growth media (DMEM with 10% v/v fetal calf serum, 2 mM L-glutamine, 100 Units/ml of Penicillin G and 100 μg/ml Streptomycin) for 48-72 hours at 37°C in humidified 5% CO 2 incubators.
Our finding that 24 h exposure to 4-AP decreased the number of viable GC in serum-free but not serum-supplemented primary cultures is consistent with the reported effects of 4-AP and other K +channel antagonists on other cell types [ 8 43 44 ] . It has been shown that the concentrations of K +channel antagonists required to inhibit growth of human bladder tumor cells can be 70 times higher in the presence than the absence of serum [ 43 ] . 4-AP has been shown to inhibit the proliferation of human myelobastic leukemia cells by preventing growth factor activation of mitogen activated protein kinase (MAPK) pathways [ 42 ] . This mechanism may be responsible for the anti-proliferative effect of 4-AP manifest in Table 1. It is likely that MAPK pathways are less robust in GC grown in defined serum-free vs. serum-supplemented media; however, validation of this hypothesis would require additional experiments beyond the scope of the present investigation.
Confluent MGBE were fed serum-free medium.
1 His-C (control) was mixed with 50 μl of serum-free RPMI (Roswell Park Memorial Institute) medium.
All cultures were grown in serum-free Neurobasal medium (2 ml per dish) supplemented with B27 (Gibco BRL, Grand Island, NY; 50:1 v/v), 0.5 mM L-glutamine (Sigma) and 100 units/ml penicillin-streptomycin (Gibco; Cat.
