The need to screen Dengue virus and Zika virus NS1 kits for cross-reactivity against other flavivirus NS1 proteins has driven the creation of the flavivirus NS1 protein pack. These packs contain a vial from each of the other four important flavivirus NS1’s (Yellow Fever Virus, West Nile Virus, Japanese Encephalitis Virus and Tick-borne Encephalitis Virus). The flavivirus NS1 protein pack is perfect for creating an immediate screening capability for antibody cross-reactivity against multiple flavivirus NS1 proteins, all correctly folded and glycosylated to represent the native state. ||Recombinant Flavivirus hexameric NS1 proteins from YFV, JEV, WNV and TBEV produced in mammalian HEK293 human cells at greater than 95% purity. Proteins contain a C-terminal 6x His-tag. ||Components (Pack of 4x100ug):|Each pack contains 1 vial each of:|397642: from strain SA-14, 1x100ug|242957: from strain Neudoerfl, 1x100ug|397649: from strain NY99, 1x100ug|353526: from strain 17D, 1x100ug||Storage and Stability:|Aliquot to avoid repeated freezing and thawing and store at -70°C. Aliquots are stable for 6 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
