Antibody:	HNMP-1 antibody
Detection system:	Secondary antibody coupled to horseradish peroxidase

Structure	Level	Pattern	Image	Note
TS20: spinal cord	Present	Regionally restricted	6A	Expression was detected in a lattice-like pattern of fibers that course from pia mater through differentiating neurons to the central canal.
TS20: spinal cord floor plate	Strong		6A

Structure	Level	Pattern	Image	Note
TS24: spinal cord	Present	Regionally restricted		Expression was detected in the somas of alpha-motoneurons in the ventral spinal cord as well as in the cores of fibers in the developing white matter.

Structure	Level	Pattern	Image	Note
TS28: spinal cord	Present	Regionally restricted	6C	Expression was detected in the alpha-motoneurons.
TS28: spinal cord white matter	Present	Regionally restricted	6C	Expression was axon-associated in fiber tracts of the white matter.

Structure	Level	Pattern	Image	Note
TS20: dorsal root ganglion	Present	Regionally restricted	6D	Expression was detected in a small subset of cells whose somas and cell processes were positive.

Structure	Level	Pattern	Image	Note
TS28: dorsal root ganglion	Present	Regionally restricted	6F	Expression was detected in the lumbar 4 dorsal root ganglion in many large sensory neurons and articulating fibers.

Structure	Level	Pattern	Image	Note
TS28: sciatic nerve	Present	Regionally restricted	8A	Expression was axon-associated with undulating positive fibers that were tangentially sectioned.

Structure	Level	Pattern	Image	Note
TS28: sciatic nerve	Present	Regionally restricted	8D	In cross section, expression was detected in the axon core, whereas surrounding myelin sheaths were uniformly negative.
