Vitamin C Analysis Service

Vitamin C is also known as L-ascorbic acid and ascorbate (the anion of ascorbic acid), which is an essential nutrient for human beings and other animal species. The opposite D-enantiomer called D-ascorbate has equal antioxidant power with L-ascorbic acid, but does not exist naturally and has no physiological function.

Scientists at Creative Proteomics utilize a highly quantitative method with high-performance liquid chromatography (HPLC) for the determination of Vitamin C levels in various samples, including Tissue and more. High-Performance Liquid Chromatography (HPLC) with UV detection is used for the determination of Vitamin C (254 nm) levels in a lot of biological samples. This Methodology provides accurate, reliable, and reproducible results of Vitamin C measurement, which enables us to analyze of Vitamin C levels in vitro and in vivo.

In humans, Vitamin C is essential to a healthy diet as well as being a highly effective antioxidant, acting to lessen oxidative stress; a substrate for ascorbate peroxidase in plants (APX is plant specific enzyme), and an enzyme cofactor in at least eight enzymatic reactions, including several collagen synthesis reactions that, when dysfunctional, resulting the most severe symptoms of scurvy. In animals, these reactions are especially important in wound-healing and in preventing bleeding from capillaries. Ascorbate may also act as an antioxidant, protecting against oxidative stress. Vitamin C is reported in high concentrations in immune cells, and is consumed quickly during infections. The mechanism of how Vitamin C interacts with the immune system is not clear, and it has been hypothesized to regulate the activities of phagocytes, the production of cytokines and lymphocytes, and the number of cell adhesion molecules in monocytes.

The Russian-Polish botanist M. Tswett is generally recognized as the first person to establish the principles of chromatography. In a paper he presented in 1906, Tswett described how he filled a glass tube with chalk powder (CaCO3) and, by allowing an ether solution of chlorophyll to flow through the chalk, separated the chlorophyll into layers of different colors. He called this technique “chromatography”. Fundamentally, chromatography is a technique used to separate the components contained in a sample. High Performance Liquid Chromatography (HPLC) is a method able to separate non-volatile, thermally unstable, and polar components separate or in a mixture. HPLC is a type of chromatography that, because of its wide application range and quantitative accuracy, is regarded as an indispensable analytical technique, particularly in the field of organic chemistry. It is also widely used as a preparation technique for the isolation and purification of target components contained in mixtures.

From Our Clients

"I recently used their proteomics service for a project analyzing protein interactions in yeast models. The team was very responsive and helped clarify the methodology they employed, which made me feel confident in the results. The data quality was solid, with clear identification of several key proteins involved in our study. Their thorough analysis enabled me to pinpoint specific interactions that I hadn't considered before, which significantly improved the direction of my research. I appreciate their professionalism and support throughout the process."

Sarah Thompson, University of California, Berkeley

"Our lab collaborated with them on a project studying cancer biomarkers. The proteomics analysis provided was detailed and focused, specifically highlighting the differential expression of proteins between healthy and tumor samples. Their clear explanations of the data helped my team understand the biological implications. I also appreciated their willingness to revise the reports based on our feedback, ensuring that we had everything we needed for our publication. This collaborative spirit was invaluable."

Emily Rodriguez, Stanford University

"Our lab worked with them on a project studying the effects of diet on gut microbiota using proteomics. They used a label-free quantification method to analyze proteins in fecal samples before and after dietary intervention. The results showed significant changes in protein expression linked to microbial activity. This was pivotal for our hypothesis about diet-microbiota interactions. The clarity of their data presentation made it easy for our team to integrate these findings into our ongoing research."

Dr. Lisa Wong, University of Toronto

"My experience with Creative Proteomics during the mass spectrometry analysis was excellent. We sent in human saliva and mouse brain tissue samples, which they expertly analyzed using both LC-MS and GC-MS techniques. The results were invaluable, revealing key metabolites in the saliva and identifying biomarkers linked to brain function in the brain tissue."

Dr. Emily Carter, Senior Research Scientist

"The overall service from Creative Proteomics was outstanding. They made the entire process seamless and efficient, allowing us to focus on our research. We worked with leaf and root samples from various Arabidopsis genotypes for targeted metabolomics analysis. Their thorough profiling of primary and secondary metabolites gave us important insights into how the plants respond metabolically to environmental stress."

Dr. Laura Henderson, Plant Physiologist

"We had a pleasant collaboration with Creative Proteomics on mass spectrometry analysis of lipids. They conducted a detailed analysis of lipid species, providing us with important insights into lipid metabolism and its relationship with metabolic syndrome disease states."

Dr. Sarah Mitchell, Research Scientist
