Lifespan Technologies, founded in 2004, is dedicated to the development of diagnostic and testing products and continues to expand its product portfolio. The company offers ELISA kits for the detection of heparin (LMWH and UFH), dextran, dextran sulfate, dermatan sulfate, and heparan sulfate. Its products are designed to deliver reliable and reproducible results, high target specificity and accuracy, rapid validation in new laboratory settings, and convenient high-throughput handling in a 96-well plate format. Depending on the kit type, only 10–100 μL of sample is required, and a full assay can typically be completed within 1–3 hours. Official product information lists Heparin Assays, Dextran Assays, Dextran Sulfate Assays, Dermatan Sulfate Assays, and Heparan Sulfate Assays as its main product categories.

●Heparin Detection
Lifespan Technologies has proprietary technology based on a novel heparin-binding protein. Its heparin assay products are used in applications such as clinical diagnostics, therapeutic drug monitoring, heparin clearance studies, assessment of susceptibility to heparin-induced thrombocytopenia, pharmacodynamic and pharmacokinetic studies, and pharmaceutical quality control. Official products include ELISA kits for both low molecular weight heparin (LMWH) and unfractionated heparin (UFH).
●Dextran Sulfate Detection Kits
Dextran sulfate can be conveniently quantified using the company’s DS ELISA series. These kits are especially useful in process quality control, including monitoring the removal of dextran sulfate in mammalian cell culture workflows used for pharmaceutical protein production. Lifespan Technologies describes its DS ELISA series as a standard solution for this application area.
●Dextran ELISA
Lifespan Technologies offers direct quantitative ELISA assays for dextran detection. These assays are particularly useful in the sugar industry for quality control of incoming cane or beet feedstocks, as well as for process testing of dextran contamination in mills and refineries, and for quality control of sugar used in food and beverage production. Official product pages list both standard Dextran ELISA and Dextran ELISA for Sugar Processing.
●Dermatan Sulfate Assays and Heparan Sulfate Detection
The company also offers assay products for dermatan sulfate and heparan sulfate detection. Official product listings include Dermatan Sulfate ELISA formats for buffer and plasma, as well as Heparan Sulfate ELISA kits for plasma and stable liquid kit formats for buffer samples.
