Figure Lengend Snippet: The area of cells in the ENS was calculated in SJL mice immunized with MSCH EAE or control mice. Three different cell markers were used. (A), There was no difference in the percentage of pixels per ganglion that expressed neuron HuD, (control n = 5, EAE n = 5, n.s.) B) There was no difference in the percentage of pixels per ganglion that expressed the glial protein S100β, (control n = 5, EAE n = 5, n.s.) C) There was a significant reduction in the distribution of GFAP within ENS ganglia of EAE mice compared to control mice (control n = 5, EAE n = 5, P < .012). Data represented as mean ± SEM and analyzed by 2-tailed Welch’s t test. Five ganglia were imaged per animal. Representative images demonstrate the distribution of HuD, S100β and GFAP in control mice (D, E, F) and EAE mice (G, H, I), respectively

Figure Lengend Snippet: Patterns of serum immunoreactivity of MS and EAE serum against ENS structures of guinea pig LMMP. MS patients who experience constipation include glial-predominant and neuronal-predominant staining. (A) Example of an MS patient serum sample that co-localizes with S100β antibodies. (B) Example of an MS patient serum sample that co-localizes with HuD antibodies. Immunoreactivity of mouse serum against guinea pig LMMP. (C) Naïve B6 control mice (top) and CFA-treated B6 control mice (bottom) do not exhibit positive immunoreactivity against cells of the ENS. D) EAE B6 + MOG-treated mice demonstrated immunoreactivity against ENS neurons (top) or against neurons and glia (bottom). Images shown at 20x magnification

Article Title: Characterization of Antibodies that Detect Human GFAP after Traumatic Brain Injury

doi: 10.4137/BMI.S9873

Figure Lengend Snippet: Lysates from the indicated sources were digested with increasing amounts of rat capn2 (triangles) and probed with the antibodies labeled on the right. Spectrin served as a positive control for digestion efficiency, and was cleaved to SBDP150 and SBDP145 in a capn2 concentration-dependent manner. ( A ) In lysates from human HEK293 cells over-expressing human GFAP, both antibodies detected GFAP from 50–38 kDa, with capn2 cleaving GFAP to a 38 kDa limit fragment. ( B ) The anti-GFAP Detection antibody recognized full length endogenous GFAP and capn2-generated GFAP-BDPs from rat and mouse brain, while the Capture antibody did not.

doi: 10.4137/BMI.S9873

Figure Lengend Snippet: ( A ) Control (normal, non head-injured) human post-mortem brain lysate (20 μg/lane) was separated by SDS-PAGE, blotted, and probed in parallel with the anti-GFAP Capture and Detection antibodies, which yielded similar banding patterns from 50–38 kDa. ( B ) Recombinant full length human GFAP (rhGFAP) was purified from E. coli , and then 4 μg was loaded and visualized with Coomassie stain. Also, 50 ng/lane was loaded, and blots were probed with the anti-GFAP Capture or Detection antibodies, which showed predominantly 50 kDa protein. ( C ) rhGFAP was cut or not with rat calpain-2 (capn2), then blotted at 50 ng/lane and visualized with the anti-GFAP Detection antibody. Capn2 digestion of rhGFAP yielded bands from 50–38 kDa.

Figure Lengend Snippet: Equal aliquots of CSF drawn at one day after injury from 8 severe human TBI patients were blotted and probed with the anti-GFAP Detection antibody. CSF from one representative control patient is also shown. Full length GFAP and GFAP-BDP were detected from 50–38 kDa. All samples were run together on the same gel/blot; intervening lanes were removed.

Figure Lengend Snippet: Immunoprecipitations (IP) were performed with biotinylated anti-GFAP Capture antibody and streptavidin (SA)-coupled beads (Capture SA IP) or with SA beads only as a negative control (SA IP only). GFAP was immunoprecipitated separately from two sources, human post-mortem brain lysate ( A ) or CSF pooled from 3 severe TBI patients ( B ). Samples of brain lysate or CSF were resolved prior to IP (pre lane 1), and after IP (post lanes 2, 5). Proteins were eluted from the SA beads (eluate lanes 3, 6), and then the beads were washed with SDS-PAGE buffer (wash lane 4). Blots were probed with anti-GFAP Detection antibody. ( A and B ). Biotinylated anti-GFAP Capture antibody recovered full length GFAP and GFAP-BDP from human brain lysate and TBI CSF, without appearing to enrich for any particular GFAP band.
