Toehold Switch with Invertase as Expression Protein (or146_B) is an RNA-based device that is to apply as a biosensor for miRNA. This biosensor is designed to detect and reflect the amount of miRNA-146 through the expression of Beta-Fructosidase (Thermotoga Maritima MSB8) (BBa_K3431000), which can convert sucrose into glucose in a time-saving process and its result can be easily represented in the readout of glucose meter. The mechanism for detection relied on the following part - Toehold Switch for miRNA-146 (or146_B) (BBa_K3431038) - whose restriction on the expression of invertase can be liberated upon binding with miRNA-146. Furthermore, we include T7 promoter (BBa_I719005) and terminator (BBa_K731721) to ensure that our device can transcribe and translate in the environment of PURExpress in vitro protein synthesis kit. | Toehold Switch with Invertase as Expression Protein (or146_B) is an RNA-based device that is to apply as a biosensor for miRNA.

Description
Toehold Switch with Invertase as Expression Protein (or146_B) is an RNA-based device that is to apply as a biosensor for miRNA. This biosensor is designed to detect and reflect the amount of miRNA-146 through the expression of Beta-Fructosidase (Thermotoga Maritima MSB8) (BBa_K3431000), which can convert sucrose into glucose in a time-saving process and its result can be easily represented in the readout of glucose meter. The mechanism for detection relied on the following part - Toehold Switch for miRNA-146 (or146_B) (BBa_K3431038) - whose restriction on the expression of invertase can be liberated upon binding with miRNA-146. Furthermore, we include T7 promoter (BBa_I719005) and terminator (BBa_K731721) to ensure that our device can transcribe and translate in the environment of PURExpress in vitro protein synthesis kit.
