Overview
Peptides play a pivotal role in modern biopharmaceuticals. As the demand for peptides continues to grow, ensuring their quality and safety becomes critical. Our company offers comprehensive peptide quality control testing services to meet the stringent requirements of the biopharmaceutical industry.
Our Services
Our services are mainly as follows:
Solubility Test
Solubility testing is crucial for evaluating the ability of peptides to dissolve in various solvents, which directly impacts their formulation and bioavailability. Our company provides you with professional solubility test services.
Counter Ion Quantification Analysis
In peptide formulations, counter ions can significantly impact stability, solubility, and overall product performance. Therefore, quantifying their concentration is essential for ensuring product quality, efficacy, and regulatory compliance. Our company uses techniques such as ion chromatography to quantitatively determine the concentration of counter ions in peptide formulations.
Amino Acid Analysis
Amino acid analysis can be used to determine the composition and content of amino acids in peptide-containing samples. Commonly used methods for amino acid analysis at our company include ion exchange chromatography (IEC), high performance liquid chromatography (HPLC), and ion chromatography (IC).
Peptide Content Analysis
Peptide content analysis, also known as peptide quantification or peptide assay, is a laboratory technique used to determine the concentration or content of peptides in a given sample. Our company provides accurate and precise peptide content analysis services. This service ensures the quality, efficacy and safety of peptide-based products and facilitates their successful development and commercialization.
Endotoxin Control and Analysis
Our company employs state-of-the-art endotoxin control and analysis techniques, such as Limulus amebocyte lysate (LAL) assays, to detect and quantify endotoxin levels in peptide formulations.
Moisture Content Analysis
Moisture content will significantly affect the stability and shelf life of peptide products. Our company uses a precise moisture content analysis method to achieve the purpose of testing.
pH Test
The pH value plays a critical role in peptide stability, solubility and bioactivity. Our company uses an accurate pH meter and electrode for pH testing to measure the acidity or alkalinity of the peptide formulation.
Stability Test
Our company conducts comprehensive stability testing studies, including accelerated stability testing and real-time stability monitoring, to evaluate the effects of factors such as temperature, humidity, and light on peptide integrity.
Peptide Sequencing
Peptide sequencing is indispensable for elucidating the primary structure and sequence of peptides, which is crucial for understanding their biological activity and therapeutic potential. Our company utilizes advanced peptide sequencing techniques such as Edman degradation, mass spectrometry to determine peptide sequences.
