Description
Technical Overview: Acid Blue 90 (CAS 6104-58-1)
Acid Blue 90 (CAS 6104-58-1), carrying the molecular identity of \(C_{47}H_{48}N_{3}NaO_{7}S_{2}\) and a weight of 854.02, functions as a highly versatile triphenylmethane acid dye across both the life sciences and industrial compounding sectors. Within laboratory registries and trade directories, this organic salt is universally recognized under synonyms including Coomassie Brilliant Blue G-250 (CBB G-250), Brilliant Blue G, and Color Index designation C.I. 42655. Physically, this chemistry presents as a dense, dark blue-violet-brown crystalline powder that dissolves smoothly in water and ethanol matrices to generate a brilliant blue liquid vehicle.

Advanced Biochemical & Surgical Fields of Use
1. Precision Protein Analytics & Gel Electrophoresis
In bio-analytical workflows, this triphenylmethane matrix operates as the irreplaceable active core of the classic Bradford protein assay. The mechanism relies on a rapid, charge-dependent binding kinetic with basic and aromatic amino acid residues, shifting the maximum absorption wavelength to standard blue levels. For SDS-PAGE workflows, it serves as a highly sensitive protein stain, delivering detection thresholds roughly three times more sensitive than traditional Naphthol Blue Black. When formatting gel protocols, using this dye eliminates the need for harsh methanol-acetic acid destaining baths while preventing background color interference.
2. Specialized Ophthalmic Surgery & Receptor Mapping
Beyond basic laboratory assays, the FDA has cleared this purified vital dye for intricate vitreoretinal procedures. Retinal surgeons introduce the sterile fluid directly into the eye to selectively stain and visualize the transparent internal limiting membrane (ILM) during macular hole closures and epiretinal membrane peelings. Furthermore, neuropharmacologists utilize the molecule as a potent, selective antagonist of the \(P2X_{7}\) purinergic receptor, tracking an \(IC_{50}\) binding affinity of 10 nM for rat models and 2000 nM for human cell lines to map inflammatory and neurological disease pathways.
3. Industrial Dyeing & Household Compounding
Within bulk material processing lines, this acid dye delivers excellent exhaust rates on nitrogenous substrates, making it an industrial staple for tinting wool fibers, raw silk yarns, nylon synthetics, and leather goods. Chemical blenders also funnel trace amounts—typically ranging from 0.0001% to 0.5% by weight—into liquid soaps, laundry detergents, recycled paper pulps, and commercial adhesives. While the structural core maintains stable color performance across a broad operational pH window of 3.0 to 9.0, it features a moderate lightfastness rating of 2–4 on standard fading scales.

Why Choose zhishangbio as Your Acid Blue 90 Supplier?
1. Dual-Tier Inventory & Constant Spot Buffers
We shield your procurement timelines from sudden market shortages by maintaining a constant 45-metric-ton inventory buffer at our centralized climate-controlled warehouses. We partition our stocks into separate high-purity, low-ash biological research grades (ideal for Bradford assays and SDS-PAGE kits) and high-exhaust industrial dyeing grades. This massive infrastructure allows us to ship small laboratory verification packages within 48 hours, while major commercial freight movements clear our loading dock in 5 to 7 business days.
2. Advanced Low-Salt Desalting Technology
Our manufacturing assets utilize an advanced, multi-stage membrane filtration and recrystallization sequence that drives active chemical content up to a strict minimum purity threshold of ≥98.0%. This technical edge drops trace salt and heavy metal contaminants down to negligible parts-per-million (ppm) levels, completely preventing background interference or baseline drift inside your spectrophotometer cuvettes. Every shipment arrives backed by a lot-specific Certificate of Analysis (COA), ensuring total batch-to-batch repeatability for your formulations.
3. Streamlined Regulatory & Export Compliance Paperwork
We completely remove the logistical headache from cross-border dangerous goods and chemical transportation. Our experienced export desk manages all localized GHS-compliant safety data sheets (MSDS/SDS), customs chemical declarations, and ISO quality manifests upfront to guarantee a hassle-free port clearance. Whether your mixing hoppers are configured for standard 25kg multi-wall moisture-proof bags, heavy-duty fiber drums, or custom smaller-scale packs, your cargo arrives hermetically sealed against humidity and caking.

FAQ
Coomassie G-250 (Acid Blue 90) is used in the Bradford protein assay and as a protein stain in SDS-PAGE. Coomassie R-250 is used primarily for staining proteins in polyacrylamide gels. G-250 binds to proteins more selectively and is used for quantitative assays, while R-250 is used for qualitative detection.
