Table 1. Summary of the effects of polystyrene nanospheres in the screening experiment with lysozyme, xylose isomerase, and xylanase in combination with Crystal Screen HT.

Protein	Control	Nanosphere 50 nm
		+	−
Lysozyme (HEWL)	5	8	1
Lysozyme (HEWL, parallel)	5	9	2
Xylose isomerase (XI)	31	8	5
Xylanase (XYNII)	4	5	1

Lysozyme experiment was repeated in order to assess the repeatability and therefore appears in the table twice. Numerical value indicates how many conditions produced crystals out of 96 possible conditions in Crystal Screen HT. Control experiment contained equal amount of water instead of nanosphere solution. ‘+’ indicates crystals in the nanosphere screen only, not in the control screen. ‘−’ indicates conditions that produced crystals in the control screen but not in the nanosphere screen.
