Average Cost in High Throughput Screening: A Detailed Overview
High throughput screening (HTS) has revolutionized the drug discovery process, allowing researchers to test thousands of compounds in a short period. However, the cost associated with HTS can be a significant barrier for many laboratories. In this article, we delve into the various factors that contribute to the average cost of HTS and provide insights into optimizing the process to reduce expenses.
Understanding High Throughput Screening
High throughput screening is a method used to identify bioactive compounds from large libraries of chemical substances. It involves rapid and automated testing of these compounds to determine their potential as drug candidates. The process typically includes the following steps:
-
Compound library preparation
-
Assay development and optimization
-
HTS execution
-
Compound selection and follow-up
Each of these steps contributes to the overall cost of HTS, and understanding the factors that influence these costs is crucial for optimizing the process.
Factors Influencing the Average Cost of High Throughput Screening
The average cost of HTS can vary widely depending on several factors. Below, we discuss some of the key factors that contribute to the overall cost:
Compound Library Preparation
The cost of compound library preparation is a significant component of the overall HTS cost. This includes the cost of synthesizing or purchasing the compounds, as well as the cost of storing and managing the library. The size and diversity of the library can have a significant impact on the cost:
| Library Size | Cost |
|---|---|
| Small (1,000-10,000 compounds) | $10,000 – $50,000 |
| Medium (10,000-100,000 compounds) | $50,000 – $200,000 |
| Large (100,000+ compounds) | $200,000 – $1,000,000+ |
Assay Development and Optimization
Assay development and optimization are critical steps in the HTS process. The cost of these steps can vary depending on the complexity of the assay and the expertise required to develop and optimize it. Factors that influence the cost include:
-
Assay complexity
-
Expertise required
-
Equipment and reagents used
HTS Execution
The cost of HTS execution is influenced by several factors, including the number of compounds tested, the throughput of the screening platform, and the cost of the screening equipment. Below is a table showing the average cost of HTS execution for different throughput levels:
| Throughput | Cost |
|---|---|
| Low (1,000-10,000 compounds/day) | $1,000 – $5,000 |
| Medium (10,000-100,000 compounds/day) | $5,000 – $20,000 |
| High (100,000+ compounds/day) | $20,000 – $100,000+ |
Compound Selection and Follow-up
After HTS, the selected compounds need to be further evaluated for their potential as drug candidates. This process, known as compound selection and follow-up, can be expensive and time-consuming. Factors that influence the cost include:
-
Number of compounds selected
-
Complexity of follow-up assays
-
Expertise required
