Opn4-Cre

Background : C57BL/6Smoc

Catalog : NM-KI-200304

Strain Name : C57BL/6Smoc-Opn4em1(Cre-WPRE-polyA)Smoc

Gene Summary

Gene Name

Model Description

Cre-WPRE-polyA expression cassette was knocked into the Opn4 gene start codon site. The melanopsin gene (Opn4) encodes a functional photopigment. When crossed with a strain carrying a gene flanked by loxP sites, the flanked gene will be removed in cells expressing cre. This strain may be useful for studying circadian rhythm regulation.

Validation Data

Fig. 1 Cre-mediated recombination in the eyes of Opn4Cre/+; Rosa26tdTomato/+ mouse. TdTomato(red) expression can be detected in retinal ganglion cell layer (RGC) and inner nuclear layer of Opn4Cre/+; Rosa26tdTomato/+ mouse.

Fig. 2 Detection of tdTomato(red) in various tissues of  Opn4Cre/+; Rosa26tdTomato/+ mice. Cre mediated recombination can be detected in   the eyes, hippocampus, olfactory bulb, serous layer of the large intestine, testis, epididymis, pulmonary bronchial epithelial cells, kidney, thymus and pituitary gland. Tdtomato expression can not be observed in the cerebellum, heart, liver, spleen, muscle, skin, stomach, small intestine or submandibular gland.
