Protein A - R-Phycoerythrin (R-PE)

button 12

R-PE conjugates are made from recombinant Protein A and R-Phycoerythrin. Protein A is a 42 kDa protein originally found in S. aureus, constituted by five homologous domains which bind the Fc region of many mammalian IgGs. Its high affinity to immunoglobulins is the reason why it is largely used in biochemical research. Their interaction can be detected by the fluorescent molecule.

R-PE is a 240kDa fluorescent protein from the phycobiliprotein family that is isolated from red algae. R-PE has a bright orange fluorescence with a high quantum yield, giving a brighter fluorescence than other conventional fluorophores and phycobiliproteins.

The absorbance spectrum of R-PE covers a broad range of excitation wavelengths, and its emission maximum is at 575nm. The broad range of excitation wavelengths provides an advantage for multi-colour immunofluorescent staining or cell sorting. R-PE is used for fluorescence-based detection, primarily in ELISAs, flow cytometry, microarray assays and other applications that require high sensitivity.

We are currently the only supplier of Protein A - R-PE conjugates. All of our conjugates are produced using our Lightning-Link® bioconjugation technology, therefore providing high quality, stable conjugates for use in your application.

For added flexibility we provide the conjugates in two different pack sizes of 1mg and 100ug. Furthermore the conjugates are freeze-dried so shipping at ambient temperature is not a problem.
