Part:BBa_K732002
synCG-β + Promoter + RBS
This construct contains a strong constitutive promoter (J23119) as well as an RBS (B0034) upstream of synCG-β (K732001), and should strongly express a synthetic version of the beta subunit of human chorionic gonadotropin.
One application of this component is detection by pregnancy test.
Proof-of-principle
When heterogeneous mixture of E. coli expressing BBa_K732001 and BBa_K732002 was lysed by either sonication or T7 infection, re-folded using a literature-based protocol, and applied to NewChoice pregnancy tests (purchased from Dollar Tree), positive results were visible.
Note that (a) there was some coloration around the positive band, and (b) the pregnancy tests were left overnight for bands to become visible. We hypothesize that the delayed read-time is necessary because the folding solution interferes with band visibility.
