1. Ultra‑sensitive cooled CCD Camera: Adopts research‑grade CCD with semiconductor cooling down to below ‑45°C, which greatly suppresses dark‑current noise. It delivers high quantum efficiency within the main chemiluminescence band (400–650 nm), enabling detection of femtogram‑level (fg) HRP/AP chemiluminescent signals, ideal for Western Blot detection of extremely low‑abundance proteins.
2. Large‑aperture Prime Lens: Equipped with an f/0.95 or larger‑aperture prime lens to maximize collection of faint photons emitted from samples. Combined with a precision motorized focusing mechanism, it ensures sharp imaging for blots of varying thicknesses.
3. Intelligent Exposure and Dynamic Range: The software features a built‑in “auto‑estimated exposure” algorithm. It rapidly determines the optimal exposure time via pre‑scan to eliminate repeated trial shots. The system dynamic range exceeds 4.0 OD, allowing linear representation of both strong signals (e.g., housekeeping reference) and weak signals (e.g., target protein) in a single image without multiple‑exposure stitching.
4. Light‑tight Darkbox and Motorized Lifting Stage: The fully light‑sealed darkbox provides an absolute dark environment for long‑time exposure (up to several hours). The motorized lifting stage works in linkage with the lens for auto‑focusing, and supports multiple sample formats including chemiluminescent blots and multi‑well plates.
5. Compliant Analysis Software: The professional analysis module supports automatic background subtraction, band grayscale quantification, relative expression calculation and reference‑gene normalization. Complying with 21 CFR Part 11 regulations, the software offers user permission management, electronic signature and audit trail functions, suitable for GLP/GMP‑compliant laboratories.
