GFP Proteins Products

Ptilosarcus GFP is a highly purified, His-tagged green fluorescent protein isolated from the sea pen Ptilosarcus, offering researchers a brighter alternative to conventional fluorescent tags. With excitation and emission maxima at 495 nm and 508 nm respectively, this ~27 kDa protein delivers roughly three times the brightness of eGFP or Aequorea GFP, along with substantially higher absorption — making it well suited for applications where signal intensity matters most. Each lot runs as a single band on SDS-PAGE, reflecting the purity standard behind every NanoLight fluorescent protein. Supplied as a stable solid, it should be stored dark at -20°C (or -80°C for long-term storage) and ships at room temperature via overnight or 2-day domestic courier. Available in 1 mg and 10 mg sizes to fit both pilot studies and larger-scale work.

Renilla Reniformis GFP is a highly purified green fluorescent protein isolated from the sea pansy Renilla reniformis, giving researchers a brighter, high-purity alternative to standard fluorescent tags. With excitation and emission maxima at 495 nm and 508 nm respectively, it delivers roughly three times the brightness of eGFP or Aequorea GFP, making it a strong choice for applications where signal strength is critical. Each lot is verified as a single band on SDS-PAGE, consistent with the purity standard behind every NanoLight fluorescent protein. Supplied purified and ready for use, it should be stored dark at -20°C (or -80°C for extended shelf life) and ships at room temperature via overnight or 2-day domestic courier. Available in 1 mg and 10 mg sizes, with a Certificate of Analysis available for download.
