Due to its unique advantages, the CRISPR-Cas system has been used to develop biosensors. CD BioSciences, a premier biotechnology company, is committed to providing you with metal ion biosensor development service based on the CRISPR-Cas system.
Metal ions are essential trace elements in life processes, and they are also key factors in environmental pollution. Therefore, the rapid and efficient qualitative and quantitative detection of metal ions has become a hot topic of current interest. The CRISPR-Cas system is derived from the adaptive immune system of microorganisms such as bacteria, archaea and fungi. In the field of bioanalysis, the CRISPR-Cas system has the advantages of precise targeting and efficient cleavage of target or non-target nucleic acids, and thus can be used as an efficient biosensing tool for detecting metal ions.
Utilizing the CRISPR-Cas system's ability to specifically identify and incidentally cleave nucleic acid sequences, CD BioSciences offers metal ion biosensor development service. In addition, we also provide services for the detection of various analytes such as nucleic acids, protein biomarkers, metal ions, and small molecules.
Our DeteCasTM platform offers different strategies in metal ion biosensor development service, including but not limited to the followings.
Design of Functional Nucleic Acids | Functional nucleic acids can specifically recognize and bind target metal ions and convert non-nucleic acid signals to nucleic acid signals. We can design different functional nucleic acids for different detection targets, such as aptamers and DNA enzymes, as recognition elements in biosensors. |
Optimization of gRNA Design | The gRNA sequence characteristics and design location are critical factors in determining the specificity, loading, shear activity and stability of the CRISPR-Cas biosensing system. We can design different gRNA sequences for the gene targets of different nucleic acids to be tested to improve the detection specificity. |
Selection of Different Signal Amplification Strategies | For metal ion detection, we can offer you different signal amplification strategies based on the CRISPR-Cas12 system and CRISPR-Cas14 system, respectively, to choose from. |
Selection of Cas Effector Proteins | High quality Cas effector proteins are the basis for establishing high performance CRISPR-Cas biosensing systems. We can screen Cas effector proteins with excellent recognition efficiency and shear activity for you and shorten the detection time. |
Design of DNA Activator | The role of DNA activators in CRISPR biosensors is to be recognized by Cas proteins and stimulate the trans-cleavage activity of Cas proteins. We can design efficient DNA activators for you. |
