Purity Testing and COA for Tirzepatide

Project Description

Dear Analytical Team,

I’m reaching out to inquire about analytical testing services for a peptide sample I have in my possession, specifically, Tirzepatide. I would like to verify both the identity and purity of this peptide through independent testing and obtain a Certificate of Analysis (COA) for documentation purposes.

I am requesting the following:
-Purity analysis, preferably by HPLC
-Identity confirmation via mass spectrometry
-Detection of any undeclared additives or contaminants, if possible
-Issuance of a COA reflecting the results

This is a single vial of lyophilized powder, purchased for research purposes. Could you please provide information on:

1. Pricing for these services
2. Required sample amount
3. Turnaround time
4. Shipping and submission instructions
5. Any necessary forms or intake process for new clients

If additional or recommended testing (e.g., amino acid sequencing, residual solvent testing, etc.) is available, I’d appreciate that information as well.

Thank you for your time and assistance. I look forward to your response.

Best regards,
Laura Johnson

Other proteins and peptides laboratory services.

Other Proteins and Peptides testing, analysis, scientific research and development, inspection, certification, engineering, failure investigation, and product development needs include :

  • Mass Spectrometry (MS): High-precision technique for protein and peptide identification quantification and structural analysis. Testing
  • Liquid Chromatography (LC): Used for the separation and analysis of proteins and peptides in complex mixtures. Testing
  • Amino Acid Analysis (AAA): Quantitative determination of amino acid composition in proteins and peptides. Testing
  • Circular Dichroism (CD) Spectroscopy: Provides information on protein secondary structure (e.g. alpha-helix beta-sheet) critical for understanding protein function and stability. Testing
  • Enzyme-linked Immunosorbent Assay (ELISA): Quantitative measurement of proteins using specific antibodies ideal for therapeutic protein production monitoring. Testing
