Description

2090339-69-6 refers to the chemical compound known as Alexa Fluor 647 COOH or AF647 Acid. Its molecular formula is C₃₅H₄₁N₂O₁₄S₄, with a molecular weight of 841.95. It is a bright far-red fluorescent dye suitable for scientific research and industrial applications, but not for medical use.

Application Fields

Alexa Fluor 647 COOH is widely used in scientific research, particularly in imaging techniques. Its excitation spectrum is well-suited for 594 nm or 633 nm laser lines, making it ideal for imaging low-abundance targets, especially in fixed cells. Additionally, it can be used in combination with DAPI and Alexa Fluor 488 and 594 dyes for multiplexing applications.

Storage Conditions and Precautions

When storing, Alexa Fluor 647 COOH must be kept away from light, in a dry environment, and at -20°C. Ensure the reagent is dry when retrieving, and avoid frequent dissolution and freeze-thaw cycles. This compound is sensitive to light and temperature; therefore, it should always be maintained under low-temperature, dry conditions to preserve its chemical properties and effectiveness.
