HemoTrial™ Kit includes 5 ml of HemogloBind™ , 5 preps of NuGel™ HemogloBind™ and 5 Preps of HemoVoid™. HemoVoid™, a silica-based protein enrichment matrix, removes hemoglobin from erythrocyte lysate samples while concentrating low abundance, and/or low molecular weight proteins. The HemoVoid™ protocol uses mild buffers; the protocol conditions are so gentle that native enzyme activity is retained in elution fractions. Poly-electrolytes are polymers with repeating units of stationary charges. HemogloBind™ comes from a class of solid-phase, or surface-based, elastomeric poly-electrolytic surfaces that bind proteins through an empirically derived chemistry combining elements of polymer composition, cross-linking architecture and charge properties. As with bio-polymers like DNA and Heparin, governing their reactivity is the spatial presentation of the electrostatic groups along a flexible polymer chain.

This study reports the use of Nanotrap® Microbiome A Particles (NMAPs) to capture and concentrate viruses from diluted suspensions to improve their recovery and sensitivity of detection. Five highly infectious animal disease viruses were used in this study. NMAPs were used to capture spiked viruses from EDTA whole blood (EWB). Virus capture from EWB was partially blocked, most likely by hemoglobin (HMB), which also binds NMAPs and outcompetes the viruses. The interference effect from hemoglobin could be removed by first using
HemogloBind™ (Biotech Support Group; Monmouth Junction, NJ), without interfering with virus capture.
