体外化合物活性的评估对药物发现工作至关重要,要求化合物准确可靠地滴定并分配到分析井中。HP D300点胶机利用喷墨技术实现小体积点胶,允许使用直接稀释模式进行浓度响应测试。虽然喷墨技术已经存在了很长时间,但它在筛选和药物开发领域是新的。我们已经在生化试验、基于细胞的报告基因试验和细胞毒性试验中评估了D300分配器。该仪器的软件是用户友好的,复合配药过程是精简的。然而,该分配器目前仅适用于96孔和384孔板格式,而不适用于1536孔高密度板。我们的结果表明,D300产生的干净和可重复的结果与使用更常用的仪器(如引脚工具)产生的结果相关。我们发现该仪器是有用的,可以提高96孔和384孔板的复合配药通量。
Evaluation of compound activity in vitro is crucial to drug discovery efforts and require that the compounds be accurately and reliably titrated and dispensed to the assay wells. The HP D300 dispenser utilizes inkjet technology to achieve small volume dispensing that allows concentration response testing using the direct dilution paradigm. While inkjet technology has been long in existence, it is new to the field of screening and drug development. We have evaluated the D300 dispenser in a biochemical assay, a cell-based reporter gene assay and a cytotoxicity assay. The software for this instrument is user-friendly and the compound dispensing process is streamlined. However, a limitation is that this dispenser is currently only applicable to 96-well and 384-well plate formats, and not to 1536-well high density plates. Our results indicate that the D300 generates clean and reproducible results that correlate with those produced with more commonly used instruments such as the pin tool. We found that the instrument is useful and can improve the throughput of compound dispensing in 96-well and 384-well plates.
