조직 용해물에서 표적 단백질을 추정하기 위한 정량적 점 블롯

Executive Industry Relevance

Quantitative dot blot (QDB) enables absolute quantification of target proteins in tissue lysates, providing high-confidence data for early discovery and target validation. Its standardized, plate-based workflow supports reproducible, quantitative protein measurement critical for portfolio triage and mechanistic de-risking. QDB's scalability and compatibility with high-throughput formats position it as a valuable asset for enterprise-level R&D decision-making.
