Hyaluronic Acid Sodium Salt from Rooster Comb – Catalog Number: B2015639 (50 mg)

Hyaluronic Acid Sodium Salt from Rooster Comb is provided as a biotechnology-grade powder in a defined 50 mg amount (Catalog number B2015639). As described by the supplier, this material is used as a molecular tool for various biochemical applications and is stored at −20 °C. The entry lists Molecular Weight or Concentration: N/A, so end-users should titrate according to their own method requirements and avoid assuming a specific molecular mass distribution. The keyword line highlights the canonical repeating disaccharide identity—Poly(β-glucuronic acid-[1→3]-β-N-acetylglucosamine-[1→4]), alternating—which reflects the well-known structure of hyaluronan.

In research environments, sodium hyaluronate is often selected for its solubility in aqueous buffers and its ability to form viscous solutions that can modulate diffusion, surface interactions, or microenvironmental properties in model systems. Within the constraints provided (no molecular weight stated), this product can be incorporated into exploratory protocols such as viscosity or rheology method development, polysaccharide binding studies, and general biochemical workflows where a defined glycosaminoglycan backbone is needed. The powder format enables flexible preparation of working stocks in user-selected buffers, while the specified storage supports maintenance of material integrity over routine research timelines. Because the supplier notes biotechnology-grade preparation with Type I ultrapure water and 0.22 µm filtration for solutions, labs can align usage with expectations for low background and reproducibility in bench protocols.

Practical considerations for use include gradual wetting and mixing to achieve uniform dissolution, filtration of working solutions where appropriate, and documentation of lot details in SOPs to support reproducibility across experiments. Typical research scenarios may involve creating viscosity standards for instrument qualification, assessing interactions between hyaluronan and proteins or small molecules, or using hyaluronan as a matrix component in proof-of-concept assays. As with any reagent labeled for research use, suitability should be verified within the intended protocol, and no clinical, diagnostic, or therapeutic applications are implied.

Why researchers choose this product:

• Convenient powder format for flexible buffer selection and stock preparation
• Defined 50 mg amount for small-scale method development and optimization
• Stored at −20 °C as specified for routine research handling
• Biotechnology-grade preparation with Type I ultrapure water and 0.22 µm filtration for solutions
• Canonical alternating disaccharide backbone (as listed in keywords) suited for glycosaminoglycan studies

This product is for Research Use Only (RUO). It is not intended for diagnostic or therapeutic use.
