Induction of atrogin 1 mRNA and protein expression by rotator cuff tear (RCT). (a) Expression of transcripts encoding the E3 ubiquitin-protein ligases atrogin 1, MuRF1, and UBR2 in injured muscle after RCT (n = 12 per group). (b) Atrogin 1 protein expression in muscle isolated at different stages after RCT (n = 7 per group). Densitometric analyses of the western blots are shown on the right. Data represent means +/- standard errors of the means. *P < 0.05. (c) Immunofluorescence (IF) microscopy analyses of muscle isolated at different stages after RCT. The red signal represents atrogin 1 protein. The negative control (secondary antibody only) for the IF showed no specific signal (data not shown). (d) Loss of AQP4 protein by overexpression of atrogin 1. C2C12 cells were treated with an adenovirus expressing atrogin 1 [Ad-atrogin 1; multiplicity of infection (MOI) = 50, 100, 200] for 48 h, and western blot analysis was performed with each designated antibody. (e) Monomeric ubiquitin protein expression in muscle cells isolated at different stages after RCT.

Aquaporin levels in the sulfatide deficient mouse brain. (A) Expression of AQP1 and AQP4 in Cre+ and Cre− cerebrum samples were measured by Western Blot and quantified (B,C). Multiple AQP4 bands with different levels of glycosylation were observed (bracket). (D) Representative immunofluorescence image for AQP4 (red) in the CST cKO mouse brain at 20 months of age. Scale bar: 250 μm. (E) AQP4 immunofluorescent area around the lateral ventricle was quantified using Image J. Unpaired two-tailed t-test (normality and equal variance were assumed/confirmed). ** p < 0.01.

Western blot results. (A) Western blot analysis of SNTA1 and AQP4 protein expression in Group C, Group PDN, and Group BHB. (B) Relative protein expression of SNTA1 and AQP4. Due to the reason that some blots in the original saved images were not mentioned in the present study, we spliced the blots and the typical ones were chosen to indicate the differences in the expression of proteins. Refer to Figure 1 for the meaning of the grouping abbreviation. Values were presented as mean +/- SEM. *p < 0.05 compared with values in Group PDN. #p < 0.05 compared with values in Group C. SNTA1 means alpha -syntrophin, and AQP4 means aquaporin-4 protein.

Application: Immunohistochemistry-ParaffinSample Tested: Brain (cerebral cortex)Species: HumanVerified Customer | Posted 12/24/2020AQP4 rabbit (1:2500) was incubated overnight at 4C on human cerebral cortex and visualised using AF Donkey anti-rabbit 488 (green).

Application: Immunohistochemistry-FrozenSample Tested: Trigeminal gangliaSpecies: MouseVerified Customer | Posted 11/22/2018Mouse trigeminal ganglion stained with aquaporin-4 antibody (1:5000 dilution).Mice were perfused with 0.9% saline and subsequently decapitated. The cerebrum was then dissected out of the cranium and the head was put in ~10mL of 4% PFA in 0.1M phosphate buffer overnight. The following morning the trigeminal ganglia were dissected and placed in 30% sucrose (sucrose dissolved in 0.1M phosphate buffer) for at least 48hr. The tissue was then blocked in OCT, frozen, cut at 10 microns (on a cryostat) and mounted on glass slides. Slides were washed three times with 1X PBS (diluted from a 10X stock (recipe available on thelabrat.com)) and blocked for 1hr in 1X PBS containing 0.2% triton X-100 and 10% goat serum. After the block, tissue was incubated overnight at room temperature in 1X PBS containing 0.2% triton X-100, 2% goat serum, 20mg/mL bovine serum albumin and the primary antibody diluted to a final concentration of 1:5000. The following morning the slides were washed twice with 1X PBS containing 0.2% tween-20 and once with 1X PBS. The slides were then incubated for 45 min (room temperature) in 1X PBS containing 0.2% triton X-100, 2% goat serum, 20mg/mL bovine serum albumin and 488-conjugated goat-anti rabbit secondary (ThermoFisher, 1:200). After the 45 min incubation period, slides were washed with washed twice with 1X PBS containing 0.2% tween 20 and once with 1X PBS. The slides were then coverslipped and mounted using vectashield mounting medium.
