Fluorescein fluorescent stability over time
WebIn real-time PCR, fluorescent DNA primers and probes offer two main advantages over DNA-binding dyes. First, these molecules specifically detect the target sequence, so nonspecific products are not detected and do not affect the accuracy of quantification.

WebThe fluorescent strength of some fluorescent tracers behaved differently in alkaline or acidic solutions. For example, the fluorescence of Brilliant Sulfaflavine (BSF) and Eosin remained nearly constant over the solution pH range of 6.9–10.4; however, Fluorescein had much higher fluorescent sensitivity than BSF and Eosin [33,34]. The ... WebInvitrogen Alexa Fluor 488 dye is a bright, green-fluorescent dye with excitation ideally suited to the 488 nm laser line.For stable signal generation in imaging and flow cytometry, Alexa Fluor 488 dye is pH-insensitive over a wide molar range. Probes with high fluorescence quantum yield and high photostability allow detection of low-abundance …
WebAug 1, 2011 · Fluorescent nanoparticles can provide a controlled microenvironment for fluorophore to protect it from unwanted chemical interactions with substrates in the external medium. In addition, the nano-containers composed of fluorescent nanoparticles have considerable advantages, such as high fluorescence intensity and good photo stability. WebThe fluorescent intensity increased 1.3 times for all three concentration solutions when the solution pH increased from 6.9 to 8.4 or higher. Similar to Fluorescein, the fluorescent …
WebThe method involves fluorescently labeling peptide molecules that would alter an organism's natural pathway. When this peptide is inserted into the organism's cell, it can induce a different reaction. This method can be used, for example to treat a patient and then visibly see the treatment's outcome.
