DPX Technologies Announces a New INTip™ Size Exclusion Chromatography Product Line

DPX Technologies, a manufacturer of laboratory consumables for sample preparation, announces the development of a new product line for size exclusion chromatography. The technology is patent-pending and utilizes a novel INTip swelling method that supports a hands-off approach for size exclusion chromatography workflows. The automated INTip swelling process allows the gel resin bed to be prepped and ready for sample application in less than 20 minutes.

Size exclusion chromatography (SEC), also known as gel filtration, is a method by which molecules pass through SEC resin media and are separated by their size. The DPX methodology uses a group separation technique for desalting and buffer exchange where small molecules such as salts are separated from a group of larger molecules such as proteins. Desalting and buffer exchange are commonly used prior to affinity chromatography for antibody purification or polymerase chain reaction (PCR) cleanup. The new product line includes SEC pipette tips and automation accessories, offering a highly reproducible, automated solution for proteomics applications.

Antibody testing and PCR cleanup are highly conversed topics due to the COVID- 19 pandemic, and DPX is committed to developing products that simplify and automate complex sample preparation for biological matrices. “This new product, along with INTip filtration products for Tip-on-Tip solid phase extraction, will help laboratories that need high throughput methods for processing thousands of samples daily, ” said Dr. Matthew Fitts, lead molecular biologist at DPX Technologies.

DPX has been manufacturing pipette tips for sample preparation since 2007 and specializes in developing custom workflows for a diverse client base.
