The service offering at Alfa Cytology
- Peptide physical chemistry analysis
Analyzing the physical and chemical properties of peptides is an important fundamental part of the early stages of peptide drug discovery, guiding the drug discovery team to identify compounds with optimal efficacy, PK, and safety. We offer peptide drug physiochemical analysis, including but are not limited to turbidimetric solubility, thermodynamic solubility, chemical stability, chemical purity, etc.
- Peptide bioanalytics and formulation analysis
Bioanalysis and formulation analysis plays an essential role in determining the concentration of various pharmacodynamic biomarkers, metabolites, and biological fluids in peptide drug discovery and development. We offer endotoxin control, solubility testing, and TFA removal services based on our best-in-class technology.
- Peptide targeting assessment in vitro and in vivo
Fluorescence imaging and flow cytometry are employed to assess the targeting property of the selected peptides in vitro. In addition, we can also evaluate the binding affinity of peptides to PC cells in vivo using an in vivo imaging system.
- Effect of the peptides on PC cells and mitochondria
To assess the toxic effects of the peptide on PC cells, an MTT assay is employed. In addition, we usually use flow cytometry, mitochondrial membrane potential assessment and WB to determine the mechanism of peptide action on cancer cells.
- Effect of the peptides on PC tumor growth in vivo
We evaluate the inhibitory effect of the peptide on tumor growth in nude mice by using the relative tumor growth rate (T/C) combined with the change in body mass.
- Systemic toxicity in vivo
To assess the toxicity of the peptide to the body, we measure hematological parameters (WBC, RBC, PLT, and HGB) and liver enzymes (ALT and AST) in nude mice, followed by a sampling of vital organ tissues for sectioning, HE staining, and analysis.
Alfa Cytology can meet the needs of our global clients by providing peptide drug validation and evaluation services on time and on budget.
