Acid Blue 90, more commonly recognized by its laboratory moniker, Coomassie Brilliant Blue G-250, is a staple in many scientific and industrial settings. This triphenylmethane dye, identified by CAS number 6104-58-1 and Colour Index number 42655, offers a unique blend of utility. Its vibrant dark blue-violet-brown hue in solid form belies its diverse applications, from critical protein analysis in biochemistry labs to providing rich coloration in industrial textiles and leather goods. As a leading chemical manufacturer, we aim to provide comprehensive insights into this versatile compound and guide potential buyers on where to purchase it.

The Core of Protein Analysis: Bradford Assay and Electrophoresis

In the realm of life sciences, Acid Blue 90 is indispensable. Its primary role is in protein quantification, most notably through the Bradford assay. This method leverages the dye's property to shift its absorption maximum upon binding to proteins, allowing for rapid and relatively sensitive concentration determination. Researchers often buy Acid Blue 90 specifically for this purpose, relying on its accuracy and ease of use. Furthermore, it serves as an effective stain for proteins separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Its ability to stain protein bands with minimal background color aids significantly in visualizing and analyzing protein profiles after separation. The consistent quality from a reliable Acid Blue 90 supplier is key to obtaining reproducible results in these demanding applications.

Beyond the Lab: Industrial Applications

The utility of Acid Blue 90 extends beyond the laboratory bench. As an acid dye, it possesses affinity for proteinaceous and polyamide fibers. This makes it a valuable colorant in the textile industry, particularly for dyeing wool and silk, where it imparts a deep, attractive shade. Its application also extends to leather dyeing, contributing to the finished appearance of leather products. For industrial users, sourcing a consistent and cost-effective supply is paramount. Purchasing directly from a manufacturer or an established exporter in China can provide access to bulk quantities at competitive prices, ensuring operational efficiency.

Emerging Roles in Research: P2X7 Receptor Antagonism

Intriguingly, Acid Blue 90 has also demonstrated potential as a selective inhibitor of the P2X7 purinoceptor channel. This property has opened avenues for its use in biochemical and pharmacological research, particularly in studies related to neurological disorders and inflammation where P2X7 receptors play a significant role. While this application is more specialized, it underscores the compound's versatility. For those seeking this specific biochemical tool, identifying a supplier that can provide the required purity and grade is essential.
