Example sentences for: cell-free

How can you use “cell-free” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • To identify whether PfPP5 is actually expressed in the parasite, cell-free extracts of the asynchronous erythrocytic stage parasites were subjected to standard chromatographic procedures that had been previously optimized for human PP5 [ 18 ] . Studies of mammalian PP5 have revealed that the TPR domain might act as an auto-inhibitory domain of the phosphatase activity, and that tryptic digestion of PP5 causes loss of the TPRs and concomitant stimulation of activity [ 19 20 21 ] . As described under Materials and Methods, the purification was in fact monitored by assaying for a trypsin-activated phosphatase with the assumption that PfPP5 may behave like mammalian PP5 in this regard [ 18 20 21 ] . As mentioned, the activity peaks always coincided with a ~69 kDa band in parallel Western analyses of the chromatographic fractions.

  • Cell-free virus was harvested, titrated and characterized by PRA and PEA prior to use in subsequent passage experiments (Figure 1).

  • The tissue was homogenized and virus stocks were prepared in MRC-5 cells from cell-free supernatants.

  • In order to determine if the increase in TNF-α mRNA after a short term stimulation with either domoic acid [1 mM] or LPS [10 ng/mL] led to a concomitant production of TNF-α protein, the cell-free media corresponding to the same microglia used for TNF-α mRNA analysis were assayed with an ultrasensitive rat-specific ELISA.

  • Cell-free membrane-binding assays
