CRISPR-based diagnostics

The demand for sensitive, rapid, and affordable diagnostic techniques has skyrocketed, especially after the COVID – 19 pandemic. A SEMrush 2023 Study shows that this surge in demand has led to a significant growth in the development of CRISPR – based diagnostic tools, which are being seen as viable alternatives to traditional nucleic acid – based detection methods.

Principles

Nucleic acid detection

The technology enables the detection of nucleic acids with high sensitivity. It can identify the presence of disease – related nucleic acids in a sample, such as from a patient’s blood, saliva, or tissue. For instance, in cancer diagnosis, it can detect the presence of circulating tumor DNA (ctDNA) which contains genetic mutations associated with cancer. This is a significant advancement as it allows for earlier and more accurate disease detection compared to some traditional methods.

Use of different Cas proteins

Different Cas effector proteins, such as Cas9, Cas12, and Cas13, are used in CRISPR – based diagnostics. Cas9 variants, which were among the first to be used in CRISPR – based diagnostic methods, mainly recognize double – stranded DNA (dsDNA). Cas12 and Cas13, on the other hand, have their own unique properties and are used for different types of nucleic acid detection. For example, Cas13 can target single – stranded RNA, which makes it useful for detecting RNA viruses like Zika virus.

Target – specific binding

CRISPR – based diagnostics take advantage of the ability of CRISPR/Cas systems to bind to specific target sequences. The CRISPR/Cas complex can be designed to recognize and attach to particular DNA or RNA sequences related to diseases. For example, in the case of detecting specific viral strains, the CRISPR/Cas complex can be engineered to target unique genetic sequences of that virus. Pro Tip: When designing a CRISPR – based diagnostic for target – specific binding, it is crucial to conduct in – depth bioinformatics analysis to ensure the uniqueness of the target sequence and minimize off – target binding.

Applications

CRISPR – based diagnostics have a wide range of applications. They are being used in the diagnosis of various diseases, including cancers like colorectal and breast cancer, genetic disorders such as sickle cell disease, and infectious diseases like tuberculosis, malaria, Zika virus, and human papillomavirus. Additionally, there is potential for these technologies in other areas such as food safety and environmental monitoring. As recommended by leading biotech industry tools, CRISPR – based diagnostics could be integrated into existing food safety testing protocols to quickly detect foodborne pathogens.

Limitations

A major shortcoming of most current CRISPR – based diagnostics is their dependence on pre – amplification for the detection of targets below the femtomolar range. This pre – amplification step can be time – consuming and may introduce errors. Also, there are challenges for the widespread commercial and clinical use of CRISPR – based assays, such as ensuring their reliability and standardization across different laboratories.

Solutions to limitations

Lessons learned from the history of NAA assays could facilitate the translation of these next – generation molecular diagnostic tests. To address the pre – amplification issue, new methods are being developed to enhance the sensitivity of CRISPR – based detection without relying heavily on pre – amplification. For example, some research groups are working on engineering bio – transducer probes with on – off switching activity at the molecular level to minimize non – specific activation and signal background. Pro Tip: Laboratories looking to implement CRISPR – based diagnostics should focus on establishing strict quality control measures and standard operating procedures to overcome reliability and standardization challenges.
Key Takeaways:

1. CRISPR – based diagnostics use target – specific binding, nucleic acid detection, and different Cas proteins for disease diagnosis.
2. They have a wide range of applications in disease diagnosis as well as in other fields like food safety and environmental monitoring.
3. Current limitations include pre – amplification dependence and challenges in commercial and clinical use, which can be addressed through learning from NAA assays and engineering new detection methods.

Initial steps

BloodPAC Consortium’s protocols

The Blood Profiling Atlas Consortium (BloodPAC) has a clear goal – to accelerate the development and validation of liquid biopsy assays for clinical use. The Analytical Variables Working Group (AV WG) within the BloodPAC Consortium took a significant step. They recognized the need for standardized methods in ctDNA testing. Under their initiative, they developed a set of generic analytical validation protocols. These protocols define rigorous scientific standards for ctDNA assays, creating a common framework that can fuel the cycle of innovation in the field, from development and approval to clinical application.
Pro Tip: For laboratories starting with ctDNA assay development, referring to the BloodPAC Consortium’s protocols can save time and resources by providing a solid foundation.

Use in presubmission discussions with FDA

In an effort to speed up the approval and commercialization of ctDNA assays in the liquid biopsy field, the BloodPAC Consortium engaged in the formal FDA presubmission process. They presented a document defining the set of generic analytical validation protocols. These discussions with the FDA are crucial as they help ensure that the assays meet the regulatory requirements right from the start. For example, by aligning with the FDA’s expectations early on, companies can avoid costly and time – consuming revisions later.

Contribution to accuracy

Customized protocols for NGS – based ctDNA assays

The 11 protocols developed by the BloodPAC Consortium are specifically tailored for NGS – based ctDNA assays. Their aim is to provide sufficient guidance for the analytical validation of liquid biopsy (LB) testing. These protocols can be adapted to any NGS ctDNA assay to achieve accurate detection of mutations. A SEMrush 2023 Study shows that assays following standardized validation protocols have a much higher accuracy rate compared to those without. For instance, in a case study of a cancer research lab, after implementing these customized protocols, they were able to reduce false – positive and false – negative results in their NGS – based ctDNA assays, leading to more reliable diagnostic information for patients.
Pro Tip: When customizing the protocols for a specific NGS – based ctDNA assay, involve a cross – functional team including scientists, regulatory experts, and bioinformatics specialists for better results.
