Northern analysis of Mcoln1. (A) Mouse fetal tissue Northern and (B) mouse multiple tissue Northern blots (Clontech) hybridized with a probe generated from exon 2 (probe 1, Fig. 1B). (C) Hybridization of the multiple tissue blot with a probe from the alternatively spliced segment of exon 13 (probe 2, Fig. 1B). β-Actin control hybridization is shown below each blot.
