WebRed fluorescent protein (RFP) is a versatile biological marker for monitoring physiological processes, visualizing protein localization, and detecting transgenic expression in vivo. RFP can be excited by the 488 nm or 532 nm laser line and is optimally detected at 588 nm. WebEasily calculate the fluorophore:protein (F:P) ratio using these 4 steps. You may need to know the amount of fluorophore conjugated to your antibody for control purposes. To …

WebThough the aptabeacons can be used as powerful biosensors, the bound protein fluorophores and quenchers are still relatively bulky. One of the advantages of oligonucleotides over proteins is their modularity, which is … Web• Fluorescent dyes are hydrophobic and may bind noncovalently to proteins. For accurate determination of dye:protein molar ratios, extensive dialysis must be performed to remove any nonspecifically bound dye. • To determine dye-to-protein molar ratio, the extinction molar coefficient (ε) of the unlabeled protein must be known. WebApr 13, 2024 · The released NPs or fluorophores are collected and detected in the supernatant. Yu et al. established a simple fluorescent method for the quantitative detection of CD63 protein in the exosomes, as shown in Figure 7A. Aptamer-functionalized MNPs were hybridized with Cy3-labeled complementary sequence (CS)-aptamers. In the … lithium ion battery energy storage
