Identification of the linear epitope for Fc-binding on the bovine IgG2 Fc receptor (boFcgamma2R) using synthetic peptides.

abstract：:A novel gene for advanced red-shifted protein with an emission maximum at 593 nm was cloned from Discosoma coral. The protein, named dsFP593, is highly homologous to the recently described GFP-like protein drFP583 with an emission maximum at 583 nm. Using the remarkable similarity of the drFP583 and dsFP593 genes, we ...
