Anti-GFP 抗体 (ab6673)

Pth4:eGFP transgenic zebrafish embryos at 1 and 2 dpf were fixed with 4% PFA and washed in PBST. They were then washed in PBDT (1% BSA, 1% DMSO, 0.1% Triton X-100 in PBS, pH 7.4), blocked in 10% normal goat serum/PBDT, and incubated overnight at 4°C with primary antibodies to HuC/D (1/100) and GFP (1/400, Abcam ab6673). Further PBST washes and blocking were followed by secondary antibodies overnight at 4°C. Hoechst 34580 was added to stain nuclei (1/2500). After further PBDT and PBS washes, embryos were mounted for confocal imaging.

Abbreviation: e, eye; hy, hypothalamus; m, midbrain; sc, spinal cord. Scale bars: 100 μm (A-C) 50 μm (D-G).

In utero electroporation of Disc1 and Disc1-100P constructs into wild-type neocortex and analysis at P21.

(Panels D-E”) Expression of the constructs was assessed.

(Panels D-D'') 2 days after transfection in vitro.

(Panels E-E'') at P21 in vivo.

Immunochemistry for FLAG and GFP showed that constructs encoding either WT Disc1, the Disc1-100P variant, or GFP alone, expressed these protein species in transfected HEK-293 cells in vitro (Fig 5D–5D”) and in P21 postmitotic cortical neurons in vivo (Fig 5E–5E”)

Immunofluorescence for assessment of GFP⁺ myofibers in rat tissue.

VML affected muscle from the 50% MG + HA+LMN group were probed for the presence of GFP. GFP+ fibers were detected in a qualitatively similar magnitude at both 2 and 8 weeks post-injury indicating viable engraftment of donor derived muscle progenitor cells. Scale bars are 1mm for whole mount images, 50 μm for regions of interest.

A portion of the TA muscle from the defect region was embedded in a talcum-based gel, frozen in 2-methylbutane, and supercooled in liquid nitrogen. Cryosections (8 μm) were prepared and stained using standard protocols for hematoxylin & eosin.

Mouse small intestines were washed with DPBS and fixed overnight at 4°C in Zinc formalin. Following sectioning and tissue deparaffanization, antigen retrieval was performed with 10mM Tris base (pH 9.0) buffer using a pressure cooker.

For immunohistochemistry, sections were quenched of endogenous peroxidases by 3% H₂O₂, and sequentially blocked with Avidin D, biotin, and protein blocking reagents. Primary antibody incubation was conducted at 4°C overnight. Secondary biotinylated antibody was added at a dilution of 1/200, and incubated 2 hours at room temperature. Finally, sections were stained according to the ABC peroxidase protocol and counterstained with hematoxylin.

Blocking Buffer: 1% Casein-TTBS for 30 min at RT.

E5.5 Hex-GFP transgenic mouse embryo stained for GFP using ab6673 at 1/500 dilution. Secondary antibody is a fluorochrome conjugated anti-goat IgG secondary antibody at 1/10,000 for 45 min at RT.

Staining: GFP as green fluorescent signal with DAPI blue counterstain.
