Antibody:	Anti-Glut1
Detection system:	Secondary antibody coupled to horseradish peroxidase

Structure	Level	Pattern	Image	Note
TS21: lower jaw molar epithelium	Strong	Regionally restricted	1A	Strong immunostaining was detected in the whole enamel organ cells. Erythrocytes showed intense staining.
TS21: lower jaw molar mesenchyme	Weak		1A

Structure	Level	Pattern	Image	Note
TS22: lower jaw molar enamel organ	Weak	Regionally restricted	1E	Enamel organ expression was gradually decreased in intensity starting at E14.5. Staining disappeared first from the inner and outer enamel epithelium as well as the enamel knot area.
TS22: enamel knot	Absent		1E

TS26: lower jaw molar enamel organ	Absent		1I

TS27: lower jaw molar enamel organ	Weak	Regionally restricted	1Q , 1M	Faint expression was detected in the inner enamel epithelium.
TS27: stellate reticulum	Strong	Regionally restricted	1M , 1Q	Erythrocytes in the stellate reticulum show intense staining.
TS27: stratum intermedium	Strong		1Q , 1M

TS28: lower jaw incisor	Strong	Regionally restricted	2E , 2B , 2H	Immunoreactivity became stronger toward the apical bud region of the maxillary incisor. Strong expression was detected in the preameloblasts and preodontoblasts.
TS28: stratum intermedium	Strong		2B , 2H
