[Immunocytochemical studies on the phase of differentiation of hatching gland cells in brine shrimp, Artemia salina].

Hatching enzyme (HE), synthesized in hatching gland cells (HGCs), plays vital roles in animal hatching. Immunocytochemical techniques employing anti-GST-UVS.2 antiserum, prepared from Xenopus HE and with specificity to brine shrimp HE, were first used to investigate the differentiation and variability of hatching gland cells (HGCs) in the hatching process of embryos of brine shrimp, Artemia salina, in this study.

Antifreeze proteins (AFPs) can highly effectively protect cells and embryos from damages in freezing process by lowering the freezing points of their cytoplasmic matrix and body fluids in a noncolligative manner. Based on their origins and properties, AFPs have been classified into four types, i.e.
