Qualitative and quantitative analysis of proteins and nucleic acids constitutes the fundamental workflow of molecular biology laboratories. Traditionally, gel imaging and chemiluminescence detection rely on separate devices with inconsistent operating logic, incompatible data formats, and divergent band quantification criteria. This not only increases laboratory procurement and maintenance costs, but also leads to signal loss and quantification deviation, compromising the data reproducibility of Western blot, nucleic acid gel electrophoresis and other molecular experiments. Our Imaging and Analysis Solution integrates core gel imaging and chemiluminescence imaging capabilities into one unified molecular imaging platform, providing one-stop image acquisition and data analysis for nucleic acid gels, protein gels, Western blot chemiluminescence and other molecular assays.
The system adopts optimized optical path designs tailored to different sample signal characteristics. For nucleic acid gels stained with EB, SYBR and other dyes, uniform LED backlighting reduces shadows and background noise, enabling clear identification of faint bands. For low-intensity transient chemiluminescence signals, a high-sensitivity cooled CCD suppresses dark current interference, captures fleeting luminous signals, avoids missed detection of weak bands, and ensures stable detection of low-abundance proteins. Equipped with automatic exposure and multi-level resolution adjustment, the system adapts to experimental scenarios ranging from rapid qualitative screening to high-precision quantitative analysis. The supporting software integrates image correction, background subtraction, band recognition, molecular weight calculation and grayscale quantification functions. It automatically identifies band boundaries and minimizes subjective manual interpretation errors, delivering traceable and archivable experimental data.
Widely applicable in molecular biology, immunology, microbiology and other disciplines, the solution supports routine and cutting-edge experiments, including Western blot protein expression detection, plasmid identification, PCR product analysis and protein gel electrophoresis imaging. In differential protein expression studies, the highly stable chemiluminescence imaging system accurately captures faint target bands and enables reliable comparison of protein expression levels across different groups. For nucleic acid detection, the gel imaging module rapidly acquires electrophoretic bands to evaluate sample purity and fragment size. The all-in-one design eliminates repeated switching between multiple devices. A single instrument covers most molecular imaging demands in conventional laboratories, saving bench space and reducing operational learning costs.
Furthermore, the system adopts a standardized data management mechanism with non-tamperable original images, complying with laboratory data normalization requirements and meeting traceability standards for academic publications and project assessments. Supporting modular upgrades, the system allows optional configuration of filters, automatic sampling modules and other accessories to fit scenarios ranging from teaching laboratories to large public research platforms. With continuously upgraded algorithms and optical technologies, our Imaging and Analysis Solution steadily improves imaging sensitivity and quantification stability, providing reliable and consistent image data for molecular biology research and enabling efficient molecular imaging and quantitative analysis for scientific researchers.
