As a leading life sciences provider, KRISHGEN BIOSYSTEMS is committed to expand our product line and more high-quality products and services for scientific research. We have the most popular and acclaimed chromatographic media in our portfolio.
According to the different separation mechanism and principle, chromatography techniques are classified into different types for separation and purification process of the various target biomolecules. There are 4 types of commonly used chromatography techniques: Affinity chromatography, Ion exchange chromatography (IEC), Gel filtration (also known as Size-exclusion chromatography (SEC) and molecular sieve chromatography), and Hydrophobic interaction chromatography (HIC).
Affinity chromatography is a powerful chromatography technique of separating and purifying proteins based on the highly specific interaction between antigen and antibody, enzyme and substrate, or receptor and ligand. Such interactions include hydrogen bonding, ionic interaction, disulfide bridges, hydrophobic interaction, etc. Affinity chromatography is widely recognized for their high selectivity, high resolution and high capacity.
Ion Exchange Chromatography
Ion exchange chromatography (IEX) is a practical chromatography process that separates ions and polar molecules based on their respective charged groups. It works on almost any kind of charged molecule—including large proteins, small nucleotides, and amino acids.
Gel Filtration Chromatography
Gel filtration chromatography, also known as size exclusion chromatography (SEC), is a chromatographic method that separates molecules by their size or molecular weight. SEC can be used for wide ranges of separation and purification of components with large molecular weight differences and low resolution requirement, such as proteins, polysaccharides and other macromolecules.
Hydrophobic Interaction Chromatography
HIC is a useful method for purification and separation of biomolecules based on their surface hydrophobicity. HIC can be applied in the separation and purification of hydrophobic proteins such as aromatic and aliphatic compounds. In HIC, the matrix material is lightly substituted with hydrophobic groups, such as methyl, ethyl, propyl, octyl, or phenyl groups.
Dr Jayaraman D. Lead Scientist, leading CRO company
I have been working with a team from KRISHGEN on an assay development and customization before giving us. The project was complicated and needed technical expertise in immunology. I was very pleased with their technical competence and also mastering immunology and delivering a tough project to us on time. Their rigor, punctuality and expertise have been a recipe for the high standards, I would expect for such project from them. Kudos, Krishgen Team!!!
Mr Ramesh Sravanan, VP-Supply Chain
The expertise and command on the logistics chain including the regulatory
guidelines from Krishgen is something we admire. As they often indicate, let us
do the supplies, and let your team focus on science … is really something the
company works on. Delivering consistently, with less than 1% error or delay
consistently is the key to their success.
Dr Keith Stevens, visiting Scientist, Norfolk University, UK
To have a company understand science and work with them, is a pleasure. Krishgen
not only sells but understands what it sells in terms of the complex cutting
Mellisa Karlowski, Lead Researcher, east coast US CRO
The company is good on understanding its customers, is transparent and
speaks science. This makes it easier for us to work with them.
