Axon fiber composition in paravertebral ganglia and related labeling in spinal cord. A. Lower power image of two caudal sympathetic ganglia and connecting nerve bridge showing nerve contains a mixture of at least 3 neurochemically distinct fiber populations: HB9-GFP+ sympathetic preganglionic neurons (SPNs), CGRP+ visceral afferents, and TH+ sympathetic postganglionics. Boxed regions are enlarged in B and C. B. Enlargement showing SPNs (GFP+), CGRP and TH immunolabeled axons in axon bundle between two ganglia. Image represents composite of 73 consecutive confocal images taken at 0.38 µm optical section thickness (27.74 µm total thickness). C. Enlargement of SPNs (GFP+), CGRP and TH immunolabeling in the left sympathetic ganglion. Section in central region of ganglia shows that, while SPNs appear to form basket-like synapses around postganglionics, CGRP+ afferents do not project through this region. Image is a collapsed stack of 11 consecutive confocal images (4.18 µm total). D. CGRP (red) and HB9-GFP labeling (green) in a transverse section of thoracic spinal cord. Note predominant CGRP labeling in the dorsal horn. HB9-GFP labeling of SPNs in the intermediolateral nucleus and motoneurons (MNs) in the ventral horn are identified on the right side. Middle panel shows CGRP labeling extending ventrally including into the intermediolateral nucleus (at arrow) while right panel provides a higher magnification image showing CGRP labeling intermingled with SPNs in the intermediolateral nucleus as well as along its medially oriented SPN projections. Scale bar is 100 µm in A, 20 µm in B and C, and 50 µm in D.

Goat anti Rat Calcitonin Gene-Related Peptide antibody used for the detection of CGRP expressing cells in rat plantar hindpaw skin by immunofluorescence.
Image caption:
Exercise training did not alter hindpaw epidermal innervation or thickness in uninjured or SNI animals. (A, B) 30 μm sections of plantar hindpaw skin were stained with ßIII tubulin (red) and CGRP (red) to quantify total and peptidergic IENF density, respectively. Arrowheads indicate IENF. DAPI (blue) staining was used to visualize the granular cell layer of the epidermis and measure epidermal thickness. (C, D) Both total (βIII tubulin+) and peptidergic (CGRP+) IENF density were unchanged by 1–4 weeks of exercise training in uninjured mice, n = 4–6. Student's t-Test. (E) 25 days after injury, a significant reduction in total (βIII tubulin+) IENF density was observed in SNI, control mice compared to uninjured controls (p<0.0001, n = 4). Exercise training for either 2 or 12 hr per night for 2 weeks did not improve hindpaw epidermal innervation following SNI. One-way ANOVA. (F) Epidermal thickness was unchanged by 1–4 weeks of wheel running in uninjured mice, n = 4–6. Student's t-Test. (G) Compared to uninjured controls, SNI, control hindpaw skin trended towards epidermal thinning that was unaffected by 2 or 12 hr/night of wheel running for 2 weeks, n = 4. One-way ANOVA. In panels E and G, mean and SEM of 2 week, 2 hr/night uninjured, controls are represented by sold and dashed lines, respectively. Data are presented as mean ± SEM. In all statistical analyses, a Bonferroni test was performed to correct for multiple comparisons.

Goat anti Rat Calcitonin Gene-Related Peptide antibody used for the detection of CGRP expressing axons in rat spinal cord sections by immunofluorescence.
Image caption:
Effects of DFO on scarring and regeneration. Tissue preservation, lesion size and axon regeneration at 19 dpl. (A) Exemplary mosaic compositions of PBS- (A) and DFO- (B) treated spinal cord stained with anti-GFAP to visualize the GFAP-negative scar area. Lesion area marked with dotted lines, Asterisks indicate a cystic area in both treatment groups. S3 Fig provides pictures A and B with higher intensity to show that the lesion site is filled with tissue. Straight lines outline the region of interest used for quantification of lesion site (2.5 mm). DFO animals had significantly smaller lesion areas (corrected for the total area) than PBS controls (C) and significantly more tissue sparing (D) and. (E) Quantification of the number of CST axons per mm2 of lesion area revealed a significant increase. (F) the CST tracing was equal in both groups. (G) The number of CGRP axons in the scar was significantly increased in DFO-treated rats. (H, I) Representative pictures of CGRP axon profiles (arrows) in the lesion area in DFO- and PBS-treated animals. Note that the red spots in I originate from aberrantly stained macrophages. Statistics: unpaired T-test * p < 0.05, ** p < 0.01. Scale bar (G, H) = 50 μm.

Blue and pink arrowheads indicate the position of the transcription and translation start sites of mouse Accn3, respectively. Red triangles represent the loxP sites. Blue boxes indicate the exons. (b) GFP signal was very low in wild-type lumbar DRG (scale bar, 50?μm). (c) Expression of GFP was much higher in the Asic3ΔEGFPf/EGFPf lumbar DRG (scale bar, 50?μm).

    • Goat anti Rat Calcitonin Gene-Related Peptide antibody recognizes Calcitonin gene-related peptide, also known as CGRP, a neuropeptide that acts as a vasodilator and plays a role in in the pathophysiology of migraine (Recober & Russo 2009). Goat anti Rat Calcitonin Gene-Related Peptide antibody reacts with both the whole molecule (amino acids 1-37) and the C-terminal fragment (23-37).
