     Cryptocyanin, a copper-free hexameric protein in crab (Cancer magister) hemolymph, has been characterized and the amino acid sequence has been deduced from its cDNA.

   • 2013, Metalloproteins—Advances in Research and Application: 2013 Edition^[1]:

     We have studied expression patterns of members of the hemocyanin gene family, hemocyanin, cryptocyanin, and phenoloxidase, in Cancer magister to better understand the molecular basis of the complex regulation and physiological transformations that occur during molting.

   • 2015, Ernest S. Chang, Physiology^[2]:

     Cryptocyanin is also synthesized in the hepatopancreas R cells.

   • 1922, Scientific American, volume 127, page 418:

     One which has recently been tried, known as cryptocyanin, makes plates so sensitive to the extreme red (at the very end of the visible spectrum, near Fraunhofer's A line) that photographs of a landscape may be obtained, with this red light, almost instantaneously.

   • 1952 May 1, Nobukatsu Shimada, “On the influence of "koha", a photosensitizing dye, against anemia caused by irradiation”, in Keio Journal of Medicine, volume 1, number 2:

     "Koha" was a cipher name of ex-army for cryptocyanin O. A., which was synthesized by Dr. T. Ogata for sensitizing the photoplate to infrared rays.

   • 1972 April 1, A. A. Kovalev, “Polarization of the induced emission from dyes”, in Journal of Applied Spectroscopy, volume 16, number 4, page 483:
