Structure and thermal stability of the extracellular fragment of human transferrin receptor at extracellular and endosomal pH.

abstract：:The red fluorescent protein, DsRed, recently cloned from coral Discosoma sp. has one of the longest fluorescence waves and one of the most complex absorbance spectra among the family of fluorescent proteins. In this work we found that with time DsRed fluorescence decreases under mildly acidic conditions (pH 4.0-4.8) i...
