Protein A - R-PE fluorescent conjugate

Innova Biosciences' Protein A - R-Phycoerythrin conjugates are manufactured using our Lightning-Link® antibody labeling technology, therefore providing extremely high quality, stable conjugates. We are currently the only supplier of Protein A - R-PE conjugates. For added flexibility we provide the conjugates in two different pack sizes of 100ug and 1mg. Furthermore the conjugates are freeze-dried so shipping at ambient temperature is not a problem.


Specificity Most mammalian IgGs
Host species E.coli and Red Algae
Format Lyophilized
Product size  100ug and 1mg total protein
Buffer Phosphate Buffer
Storage -20°C

Additional information

Protein A is a 42kDa surface protein of the bacterium Staphylococcus aureus, which binds the Fc region of many mammalian IgGs. Its high affinity for immunoglobulins is the reason that it is often used in biochemical research.

R-Phycoerythrin (R-PE) is a 240kDa phycobiliprotein that is isolated from red algae. R-PE has a bright red-orange fluorescence with a high quantum yield, and is brighter than other conventional fluophores and phycobiliproteins. The absorbance spectrum of R-PE covers a range of excitation wavelengths, which provides an advantage for multi-color immunofluorescent staining or cell-sorting. The emission maximum of R-PE is at 575nm. R-PE is used for fluorescence-based detection, often in assays which require high sensitivity.
