A qPCR 384-well plate typically has a well volume of 30-40 microliters. This 384 well plate volume range is ideal for conducting quantitative polymerase chain reaction (qPCR) experiments, providing a small but sufficient space for the reaction mixture. The small well size allows for high-throughput analysis of samples while conserving precious reagents. Additionally, the 384-well format is compatible with automated liquid handling systems, further streamlining the workflow for qPCR assays in research, diagnostics, and other molecular biology applications.
