Figure Lengend Snippet: Validation of Itgb2 expression in spinal cord tissue in vivo . (A) Schematic diagram of experiments used to validate Itgb2 expression in the C57BL/6J SCI mouse model in vivo . (B, C) Western blotting (B) and quantification (C) of ITGB2 protein expression in the sham, 1 dpi, 3 dpi, and 7 dpi groups ( n = 4 for each group). (D) qRT-PCR validation of Itgb2 expression in the sham ( n = 4), 1 dpi ( n = 4), 3 dpi ( n = 4), and 7 dpi ( n = 3) groups. (E) Counting of total number of ITGB2 + cells merged with DAPI-positive cells in F. (F) Representative immunofluorescence (IF) staining of ITGB2 (yellow, Alexa Fluor ®-555), in the sham, 1 dpi, 3 dpi, and 7 dpi groups, showing a rapid increase in the number of ITGB2-positive cells post-SCI that gradually decreased over time. Nuclei were stained with DAPI (blue). The core injury zone is outlined in each image. Scale bar: 500 μm. Areas outlined in red boxes were magnified. * P < 0.05, *** P < 0.001, **** P < 0.0001. Data expressed as mean ± standard deviation ( n = 5 for each group) and analyzed by one-way analysis of variance using Tukey’s multiple comparisons test. DAPI: 4′,6-Diamidino-2-phenylindole; dpi: day(s) post injury; Itgb2: integrin β2; ns: not significant; qRT–PCR: quantitative reverse transcription–polymerase chain reaction; SCI: spinal cord injury.
Article Snippet: After blocking with 5% non-fat milk for 1 hour, membranes were incubated overnight at 4°C with primary antibodies rabbit anti-ITGB2 (1:1000; Proteintech; Cat# 10554-1-AP, RRID: AB_2877736) and rabbit anti-β-tubulin (1:30,000; Proteintech; Cat# 66240-1, RRID: AB_2881629).
