R-Phycoerythrin

Structure: The molecular structure consists of a carrier protein linked by a thio ether bond with an open linear chain of  tetrapyrroles.

Molecular Weight: about 170,000 dalton
Purity: Amax/A280 > 5nm
Maximum absorption peak: 480/565±5nm
Fluorescence emission peak: 575±5nm

ADVANTAGES

1. It has a wide absorption spectrum within a wide PH range, which is helpful in choosing an appropriate excitation wavelength to obtain a highly efficient fluorescence emission. And there is a specific fluorescence emission peak when excited.

2. The absorbance and fluorescence quantum yield are very high. It has got a strong and stable fluorescence and high sensitivity.

3. The fluorescent background is small, and it does not quench easily. The fluorescence storage period is longer. 

4. It has excellent water solubility, which is easy to cross-link with other molecules with less specific adsorption.

5. Extracted from pure natural marine organisms, it can be applied safely with no toxic side effects or radioactivity. It is easy to combine with antibodies, biotin, affinity, immune protein and other substances to work as fluorescent probes.

APPLICATION

1. Fluorescent probe labeled antibodies, biotin, streptomycin or other proteins are widely used in immunofluorescence, immunohistochemistry, flow cytometry and in vivo imaging experiments.

2. Studies shows that phycoerythrin is a new type of photosensitive drug with high efficiency and none toxic side effects. It is expected to develop into a new type of photodynamic drug with practical value.

3. Phycoerythrin, as a natural pigment with no toxic side effects, can be widely used in cosmetics, food and health care products.
