Red Fluorescent Protein - R-PE (R-Phycoerythrin) recombinant protein

RFP, Red Fluorescent Protein, R-PE, R-Phycoerythrin

Product info
Calculated MW 240 kDa
Additional Info
Gene Symbol R-PE
Other Names RFP, Red Fluorescent Protein, R-PE, R-Phycoerythrin
Gene Source Red algae
Source Febico’s proprietary red algae
Assay&Purity Absorbance; A566/A280 ≥ 5.5
Assay2&Purity2 Absorbance; A566/A498 ≤1.5
Recombinant No
Target/Specificity R-PE
Application Notes Before use, centrifuge the R-PE suspension at 10,000g for 10 min at 4C. Discard the supernatant and resuspend the pellet (R-PE) into the desired buffer. R-PE is stored in a salt solution and it must be extensively dialyzed (Can use BioVision’s Dialyzer tubes) or desalted in columns prior to use, to remove any remaining ammonium sulphate.
Format Suspension
Storage 2-8°C ; R-PE is supplied in 100 mM Potassium Phosphate buffer, pH 7.0 with 60% Saturated (NH4)2SO4, 1 mM EDTA and 1 mM Sodium Azide.

R-phycoerythrin (R-PE) is an intensely bright phycobiliprotein isolated from red algae that exhibits extremely bright red-orange fluorescence with high quantum yields. The broad excitation spectrum provides the advantage for multi-color immunofluorescent staining or cell sorting. R-PE consists of a, b and g subunits and is present as (ab) 6g. R-PE and the closely related BPE are the most intensely fluorescent phycobiliproteins having orange fluorescence. R-PE is a large molecule used for fluorescence-based detection, primarily in flow cytometry, microarray assays, ELISAs, and other applications that require high sensitivity but not photostability. In practical applications, the sensitivity of R-PE conjugates is usually 5 to 10 times greater than those of the corresponding fluorescein conjugates.
