OFPSparkTM is a red (orange) fluorescent protein (excitation/emission maxima are 549 and 566 nm, respectively) derived from DsRed. Possessing high photostability and pH stability, OFPSparkTM is more than twice brighter than mOrange2. Fast OFPSparkTM maturation makes it detectable in mammalian cells as early as within 8 hrs after transfection. OFPSparkTM can be expressed and detected in a wide range of organisms. Mammalian cells transiently transfected with OFPSparkTM expression vectors produce bright fluorescence in 8 hrs after transfection. No cytotoxic effects or visible protein aggregation are observed. For its monomer structure, OFPSparkTM performs well in some fusions and protein labeling applications.

内毒素 | Please contact us for more information. |
缓冲液 | Lyophilized from a solution filtered through a 0.22 μm filter, containing Tris, pH 8.0.Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization. |
复溶方法 | A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information. |
存储 |
It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at-80℃. For reconstituted proteinsolutions, the solution can be stored at -20°c to -80'c for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
运输方式 |
In general, Lyophilized powders are shipping with blue ice. |
