Meanings

1. (uncountable, usually) A hexameric protein associated with moulting in crustaceans
   • 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. 1999 March 2, Nora B. Terwilliger, “Cryptocyanin, a crustacean molting protein: Evolutionary link with arthropod hemocyanins and insect hexamerins”, in PNAS, volume 95, number 5:
   • Cryptocyanin is also synthesized in the hepatopancreas R cells. 2015, Ernest S. Chang, Physiology:
   • 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. 2013, Metalloproteins—Advances in Research and Application: 2013 Edition:
2. (uncountable, usually) Synonym of cryptocyanine.
   • 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. 1922, Scientific American, volume 127, page 418:
   • We used transverse pumping in conjunction with theoretical calculations to show that the degree of polarization of the induced emission from cryptocyanin and phthalocyanin can vary from 1 to 0 in accordance with the excitation conditions. 1972 April 14, A. A. Kovalev, “Polarization of the induced emission from dyes”, in Journal of Applied Spectroscopy, volume 16, number 4, page 483:
   • "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. 1952 May 14, Nobukatsu Shimada, “On the influence of "koha", a photosensitizing dye, against anemia caused by irradiation”, in Keio Journal of Medicine, volume 1, number 2:
