Figure Lengend Snippet: Activated NR2B (Tyr1472) expression, the enhanced interaction of NR2B with Src, and changes in the levels of p-Src and p-NR2B after the administration of 4-amino-5-(4-chlorophenyl)-7-( t -butyl) pyrazolo [3,4- d ] pyrimidine (PP2) to the immature rat HI brain injury model. (A) Immunoblots showing the levels of multiple proteins. Primary antibodies are listed on the left. (B) Quantification of NR2B (Tyr1472) (p-NR2B) and NR2B levels at 2 h post injury (HI 2 h). N = 7 animals per group. (C) Coimmunoprecipitation was conducted using right hemisphere homogenates with the Src antibody or rabbit IgG as a control. Immune complexes were detected using immunoblotting (IB) with anti-Src and anti-NR2B antibodies. (D) Immunoblots showing the levels of multiple proteins. Primary antibodies are listed on the left. (E) Quantification of the levels of p-Src and Src at HI 2 h. N = 4–6 animals per group. (F) Quantification of the levels of p-NR2B and NR2B at HI 2 h. N = 4–6 animals per group. * p < 0.05 and ** p < 0.01.
Article Snippet: The blots were then blocked with 5% bovine serum albumin in TBS buffer for 1 h at room temperature and probed overnight at 4°C by incubation with the following primary antibodies: Src (1:1,000, CST, catalog number: #2123), phosphor-Src (Tyr 416, 1:1,000, CST, catalog number: #6943), NMDAR subunit NR2B (1:1,000, CST, catalog number: #14544), phospho-NR2B (Tyr 1472, 1:1,000, CST, catalog number: #4208), myelin basic protein (MBP) (1:1,000, Biolegend, SMI99), Iba-1 (1:1,000, Abcam, ab178847), glial fibrillary acidic protein (GFAP) (1:1,000, CST, 12389), β-actin (1:5,000, Absin, abs137975), and GAPDH (1:1,000, Absin, abs132004), followed by appropriate secondary HRP-conjugated antibodies (anti-rabbit, 1:5,000, Absin, abs20002; anti-mouse, 1:5,000, Absin, abs20001).
