Technical Data
R1310-01B
Red Fluorescent Protein (dsRed)
100ug
BioSeparation? Storage: -20CShipping: Blue Ice
The recombinant RFP (dsRed) was expressed and purified from transformed E. coli using a method that ensures high purity and maximal RFP fluorescence. Endotoxin was removed, so the protein is suitable for in vivo injection or cell culture applications. The protein is a 27.6kDa monomers containing a N-terminus 6x His-Tag with Ex./Em. = 557/585nm, extinction coefficient (e 280nm = 34380 M-1 Cm-1).

Endotoxin: <0.1ng/ug

Storage and Stability:
Lyophilized powder may be stored at -20C. Stable for 12 months at -20C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20C. Reconstituted product is stable for 6 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Molecular Weight:
27.6 kDa
Source: E. coli
Purity: ~97% (SDS-PAGE, HPLC)
Form: Supplied as a lyophilized powder. Reconstitute with sterile ddH2O to a concentration of 1mg/ml.
