Lactate detection

Our project aims to detect the risk of caries through three parameters: Competence stimulating peptide, CSP concentration, lactate level, pH value.

This construction is used for lactate quantization We made use of the property of LldR operon. The LldR is transcription factor. Without lactate, it will bind on O1、O2 operator site, form a DNA loop, blocking the transcription. As lactate present, lactate will bind on LldR and open the loop, allowing the transcription to go on and produce GFP. GFP intensity is then detected and deduct lactate level. This construction is cloned into E.coli.
