一、基本信息

产品简介：Biotin PEG4 Tyramide is composed of biotin, polyethylene glycol, and tyrosine. Biotin is a common vitamin B complex that can participate in protein synthesis and metabolism. Polyethylene glycol is a long-chain organic compound with good water solubility and biocompatibility. Tyrosine is an amino acid that can participate in the synthesis and metabolism of neurotransmitters.

Biotin PEG4 Tyramide can serve as a marker for labeling biomolecules such as proteins and nucleic acids. Due to its two reactive groups, biotin and tyrosine, the target molecule can be bound to Biotin-PEG4 Tyramide through specific reactions with biotin avidin and oxidative coupling reactions between tyrosine and hydrogen peroxide. In this way, the target molecule can be enriched in specific positions through a specific reaction between avidin and biotin, thereby achieving the localization and detection of the target molecule.

Biotin-PEG4-Tyramide是一种由生物素、聚乙二醇和酪胺酸组成的化合物，具有非常重要的应用价值。生物素，作为维生素B复合物的一种，它在蛋白质的合成和代谢中扮演着重要的角色。聚乙二醇，一种有机长链化合物，拥有出色的水溶性和生物相容性，使其在许多领域中都得到了广泛的应用。而酪胺酸，作为一种氨基酸，它在神经递质的合成和代谢中也起着不可或缺的作用。
Biotin-PEG4-Tyramide不仅具有生物素和酪胺酸这两个可反应的基团，而且由于其独特的化学结构，它能够与蛋白质、核酸等生物分子进行有效的标记。通过生物素与亲和素之间的特异反应，以及酪胺酸与过氧化氢的氧化偶联反应，我们可以将目标分子与Biotin-PEG4-Tyramide紧密结合。这种结合方式不仅可以实现对目标分子的定位和检测，而且还能通过亲和素与生物素之间的特异反应，将目标分子富集在特定的位置。
