Probe:	Dkk2 cDNA1
Probe preparation:	Antisense labelled with digoxigenin RNA
Assay notes:	The majority of the data are not shown. The lens development data is summarized in Table 1. The authors state that expression of this gene during ocular development was indistinguishable as was described for Dkk3 (as shown in MGI:3042136).
