Example sentences for: aptamer

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

  • The anti-theophylline aptamer was attached at the same point as had previously proven successful in the design of theophylline-dependent cleavases and ligases [ 13 14 ] .

  • In order to examine effector-specificity in vivo , a new series of Group I aptazymes was constructed in which the anti-theophylline aptamer was mutated to bind 3-methylxanthine (3MeX2P6) [ 34 ] . These variants proved to be responsive to 3-methylxanthine both in vitro and in vivo (Figure 6a).

  • The ligand specificity of the anti-theophylline aptamer carried over to the theophylline-dependent aptazyme, and no activation was seen with caffeine, which differed by a single methyl group from theophylline.

  • Based on these studies, we designed a series of Group I aptazymes in which the anti-theophylline aptamer was substituted for either a portion of P6 or P5 (Figure 1).

  • The effector specificity could be rationally changed by changing the specificity of the conjoined aptamer: when a mutation was introduced into the anti-theophylline aptamer that led to discrimination against theophylline and in favor of 3-methylxanthine (that also differed from theophylline by a single methyl group), the aptamer became solely responsive to 3-methylxanthine in vivo . Group I aptazymes may have a number of important biotechnology applications, including use as in vivo , real-time reporters and as regulatable gene therapeutics.
