In the realm of molecular biology and genetics, Psoralen (CAS 66-97-7) stands out as a critical research chemical due to its unique photochemical properties, particularly its ability to bind to DNA. This furocoumarin compound acts as a powerful molecular probe, enabling scientists to investigate complex biological mechanisms related to DNA structure, replication, and repair. Researchers frequently seek to buy Psoralen to facilitate these intricate studies.

The core mechanism behind Psoralen's utility in research involves its photochemical activation. Upon exposure to UVA light, Psoralen molecules intercalate into the DNA double helix and form covalent cross-links between adjacent pyrimidine bases. This process not only stabilizes DNA structures but also serves as a way to study the accessibility of different DNA regions and the proteins that interact with them. For instance, Psoralen cross-linking is employed to map chromatin structure and to identify specific DNA-protein binding sites.

Furthermore, Psoralen's interaction with DNA is fundamental to understanding DNA damage and repair pathways. By inducing specific types of DNA adducts, researchers can investigate the cellular machinery responsible for repairing such lesions. This has significant implications for cancer research, where understanding DNA repair mechanisms is crucial for developing effective therapies. When sourcing Psoralen for these sensitive experiments, ensuring high purity and reliable batch consistency is non-negotiable.

Scientific institutions and laboratories looking to procure Psoralen powder for their research needs can find many suppliers offering this compound. When making a purchase, it is advisable to consult with manufacturers who can provide detailed technical data and support. The price of Psoralen can vary based on purity and quantity, making it important for researchers to compare options from reputable chemical suppliers. A strong understanding of the CAS number (66-97-7) and the compound's specific applications will aid in selecting the right Psoralen product for successful research outcomes.
