![]() The chemiluminescent Western blot assay proved more sensitive than the classic colourimetric Western blot assay. With this leap in sensitivity, Stellar fluorescence detection rivals the widely recognized sensitivity of chemiluminescence detection and demolishes the fluorescence detection of the closest competing traditional Western blot imaging instrument, which requires at least 50 pg. ![]() As originally conceived by Towbin et al. Chemiluminescence is broadly defined as a chemical reaction resulting in the emission of light. Western blot detection methods have traditionally used X-ray films to capture chemiluminescence. Western blotting experiments were initially performed to detect a target protein in a complex biological sample and more recently, to measure relative protein abundance. EZ-ECL Enhanced Chemiluminescence Detection Kit for HRP. The chemiluminescent Western blot assay provided reproducible results, an objective evaluation of the results and a semi-quantitative analysis of the presence of antibodies against VP1 and VP2 in human sera. Western blotting is a powerful and commonly used tool to identify and quantify a specific protein in a complex mixture. EZ-ECL Kit for highly sensitive detection of immobilized proteins i.e. The light photons are then measured with one of two detection methods: x-ray film or digital imaging. Consequently, HRP causes the substrate to oxidize and transiently produce a signal in the presence of hydrogen peroxide (H 2 O 2 ). The potential for diagnostic purposes was evaluated using reference serum samples and 75 clinical samples from patients with different clinical conditions and laboratory evaluations regarding B19 infection. The most common chemiluminescent detection substrate, HRP, is luminol-based. The chemiluminescent WB assay combined the sensitivity of chemiluminescent substrates and the objective evaluation of the luminescent signal obtained with a new system which consists of a videocamera-based, high-performance, low light level imaging luminograph connected to a personal computer for image analysis. The theory behind several commonly used western blotting detection methods such as colorimetric, chemiluminescent and fluorescent methods, and other less common methods, such as chemifluorescence, autoradiography, and immunogold labeling methods are highlighted below. A chemiluminescent Western blot (WB) assay was developed to detect the immune status against linear epitopes of parvovirus B19 structural proteins VP1 and VP2.
