Probe:	Crabp-1 cDNA1
Probe preparation:	Antisense labelled with S35 RNA
Visualized with:	Autoradiography

Structure	Level	Pattern	Image	Note
TS16: forelimb bud	Present	Non-Uniform	1a CRABP	Expression is abundant and uniformly distributed in the posterior of the forelimb. There is a gradual proximal to distal increase in transcripts in the anterior. No labelling is seen in the proximal core of the bud; it is maximal at the distal tip.

TS16: forelimb bud	Present	Non-Uniform	1c CRABP , 1b CRABP	Expression is abundant and uniformly distributed in the posterior of the forelimb. There is a gradual proximal to distal increase in transcripts in the anterior. No labelling is seen in the proximal core of the bud; it is maximal at the distal tip.
TS16: forelimb bud apical ectodermal ridge	Present		1c CRABP , 1b CRABP	The dorsal most cells are labeled; the rest of the limb ectoderm is not.

Structure	Level	Pattern	Image	Note
TS20: forelimb mesenchyme	Present	Non-Uniform	1d CRABP	Expression is most abundant in cells underlying the ectoderm and surrounding the limb axial blood vessels; there is very little in the distal mesenchyme.
TS20: forelimb pre-cartilage condensation	Absent		1d CRABP

TS20: hindlimb mesenchyme	Present	Non-Uniform	1e CRABP	Expression is most abundant in cells underlying the ectoderm; there is very little in the distal mesenchyme.
TS20: hindlimb pre-cartilage condensation	Absent		1e CRABP
