Recombinant Chikungunya virus (CHIKV) E2 Protein

Cat. No.: rp141892
AVAILABLE TO ORDER
GRADE & PURITY Animal Free ? Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material. Carrier Free ? Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays. His Tag ? His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein. PBS Only ? PBS-only formulation — supplied in phosphate-buffered saline with no other additives. Use when you need a clean PBS buffer free of stabilizers/carriers. ≥95%(SDS-PAGE)

Biochemical and Physiological Mechanisms
Class II viral fusion protein. Fusion activity is inactive as long as E1 is bound to E2 in mature virion. After virus attachment to target cell and endocytosis, acidification of the endosome would induce dissociation of E1/E2 heterodimer and concomitant t

Reconstitution
Reconstitute in sterile distilled water to a concentration of 0.1-0.5 mg/mL. Centrifuge the vial before opening. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Storage
Store at -20°C,Avoid repeated freezing and thawing

Ice chest + Ice pads
Stability And Storage
Store at -20~-80℃ long term (1 year). Upon reconstitution, it is recommended to aliquot. Avoid freeze/thaw cycle.
