Purification & Enrichment Of Hemoglobin From Blood For Hemoglobin Variant Research Hemoglobin enrichment from fresh or frozen blood and dried blood spot/blood card etc. Enriched hemoglobin voids in flow-through >98% pure, with <30 minute bind/wash/elute protocol Disposable, cost-effective and high-throughput. Mild buffer condition maintains tertiary structure and simple transfer to secondary analysis Enriches hemoglobin from diverse species including human, sheep, mouse, goat, rat, etc. Enriched/purified hemoglobin can be studied for variant research and other research applications. Eluted fractions contains hemoglobin depleted proteins which can be used for LC-MS, proteomic studies
