<p>Indocyanine green is a fluorescent dye with a variety of applications in medical imaging. It has been used to diagnose and evaluate the activity of cancer cells and brain functions. Indocyanine green has also been used as an angiographic agent for diagnosis of solid tumours. In addition, it can be used to evaluate liver function and the blood flow in the brain. The biological properties of indocyanine green have not yet been fully elucidated, but it is known that it binds to hepatocyte-like cells in culture and is found at high levels in human serum. This dye shows fluorescence when bound to DNA or RNA, which indicates its possible use as a molecular probe for detecting carcinoma cells. <br>Indocyanine green is a STT3B inhibitor and has been shown to prevent α-amanitin toxicity in mice (Wang et al, 2023). This means it could be a possible antidote to poisoning by Amanita, such as death cap mushroom Amanita phalloides, which is the cause of over 90% of fatal mushroom poisoning.</p>

<p>羟基萘酚蓝是一种合成偶氮染料，是一种含有官能团RN=N-R的化合物。羟基萘酚蓝三钠盐和二钠盐用作分光光度法测定碱土和镧系元素含量的指示剂，最长为~650 nm（λ麦克斯= 647.6 纳米）。羟基萘酚蓝钠盐的常见用途的一个例子是通过测量钙和镁的浓度来确定水的硬度。在碱性或碱性pH值下，羟基萘酚蓝与金属离子形成粉红色/红色络合物，用EDTA滴定后，羟基萘酚蓝被释放出来，使溶液变成蓝色，指示终点。</p>

<p>C.I.Direct green 28 is a site-specific fluorescent dye that binds to guanine nucleotide-binding proteins, which are involved in the regulation of heart function and signal pathways. The α subunit of these proteins has been shown to bind C.I.Direct green 28, with a hydroxyl group on the amino terminus and an ubiquitin ligase at the carboxyl terminus. This binding inhibits polymerase chain reaction (PCR) amplification by interfering with the ubiquitin proteasome pathway, which results in decreased light emission and hematopoietic cell production. This activity is hypothesized to be due to the inhibition of ATPase activity by C.I.Direct green 28, which leads to decreased phosphorylation of E1A-activating enzyme and increased phosphorylation of E2F-repressing enzyme, preventing DNA replication through transcriptional activation of erythroid transcription factors and halting progression through G1/S phase</p>

The pigment was named for its ability to produce light emission when exposed to ultraviolet radiation. Pigment Red 38 has a diameter of 6 nm and reacts with coordination complexes to form particle clusters with diameters ranging from 10-200 nm.</p>

<p>C.I.Reactive Red 152 is a dye that is used to detect the presence of t-DNA in plant tissue and protoplasts. C.I.Reactive Red 152 has been shown to increase the frequency of germination in halophytes, such as Portulacastrum, when used at concentrations between 20 and 50 mg/l, and also has a stimulating effect on seed germination in Portulacastrum, which can be observed by an increased number of root cultures. It is extracted with an organic solvent such as dichloromethane or chloroform, and is then mixed with an equal volume of distilled water before use. The dye should be added to the culture medium just before the explants are placed into it so that it does not interfere with their metabolism. C.I.Reactive Red 152 has been found to amplify the number of rhizogenes when used at a concentration between 10 and 20 mg/l for 5 minutes, but</p>
