Precision Calibration Standard with Norleucine

This analytical-grade amino acid mixture incorporates norleucine as an internal standard, ensuring precise calibration for protein hydrolysate analysis. Each amino acid componentcarefully measured and blendedaligns with the typical hydrolysate profile, supporting robust quantification and method validation in your laboratory workflow.

Sterile and Stable for Reliable Applications

Prepared and packaged in nitrogen-purged, sealed vials or amber bottles, these standards are sterile and protected from contamination. Their lyophilized powder form ensures ease of handling and long-term stability, provided they are kept dry and refrigerated, greatly extending usability over repeated applications.

Versatile Solution for Analytical Techniques

Designed for use in HPLC, ion-exchange chromatography, and related instrumentation, this mixture fully dissolves in water or dilute acid. Whether calibrating equipment or conducting protein hydrolysate quantification, users benefit from standardized results and improved reproducibility across diverse analytical protocols.

FAQs of Amino acid standards for protein hydrolysates containing norleucine:

Q: How do I properly reconstitute the amino acid standard for protein hydrolysate analysis?

A: Accurately weigh the required amount of the lyophilized powder and dissolve it in a suitable diluentsuch as water or dilute acidimmediately prior to use. Mix gently until completely dissolved to ensure uniformity for precise calibration.

Q: What is the benefit of norleucine as an internal standard in this amino acid mixture?

A: Norleucine serves as a stable internal reference, enabling accurate quantification and compensating for instrument and sample variability, thereby enhancing the reliability of your analytical results during protein hydrolysate assessment.

Q: When should I use this amino acid standard in my laboratory workflow?

A: Use this standard during the calibration or validation stages of amino acid quantification, particularly in protein hydrolysate analyses using HPLC, ion-exchange chromatography, or similar analytical instruments to establish accurate reference curves.

Q: Where should I store the mixture to ensure maximum stability and shelf life?

A: Keep the sealed vial or amber glass bottle refrigerated at 28C, in a dry environment and tightly closed. Proper storage greatly extends the products shelf life to at least two years.

Q: What is the process for verifying the sterility and integrity of the product?

A: Each batch undergoes sterility testing to confirm the absence of bacteria and fungi. Additionally, products are packed in sealed, nitrogen-purged containers to maintain purity and prevent contamination throughout the shelf life.

Q: Can this amino acid standard be used in methods other than HPLC or ion-exchange chromatography?

A: Yes, the standard is suitable for any analytical technique that requires external amino acid calibration, provided it aligns with the solubility and stability properties of the mixture.

Q: What safety precautions should I consider when handling this product?

A: This amino acid mixture is non-poisonous, odorless, and intended strictly for analytical calibration; it is not for human or animal consumption. Avoid ingestion, inhalation, or skin contact, and handle using proper laboratory protective equipment.
