(a) Crystals of mistletoe lectin I inside a thick-walled glass capillary from a Gel Tube R (GT-R) crystallization kit used on JAXA-GCF flight No. 6 illuminated with white light. The crystal size is estimated to be 0.3 mm. (b) The same sample illuminated with UV light according to the excitation spectrum (Fig. 3). (c) Crystal of glucose isomerase obtained from a counter-diffusion crystallization experiment applying the GCB-2 Box (Triana). (d) The same crystal illuminated with UV light as in (b). |
