描述 Anti-O4 Antibody, clone 81 Alternate Names - Sulfatide
背景信息 Oligodendrocytes and astrocytes are derived from common precursor cells, glioblasts (Sommer, 1981). O-Antigens are sulfatides, which function as differentiation markers on the surface of oligodendrocytes of the central nervous system. O4 is formed postnatally (Schachner, 1981) and is a marker for cell bodies and processes of oligodendrocytes types I and II (hairy eyeball type). During oligodendrocyte differentiation, O4 occurs in pro-oligodendrocytes, but not in O-2A-progenitor cells. O4 occurs from day 3 onwards in cell cultures of embryonic mouse brain. Anti-O4 can be used in myelination, demyelination and remyelination studies and in regeneration experiments. 产品信息 格式 Purified 控制 - Rat cortical stem cells or day 3 cell cultures of brains from mouse embryos
演示 Purified immunoglobulin in 0.05M Potassium phosphate buffer, pH 8.0 with 0.3M NaCl and 0.05% sodium azide. 应用 应用 Anti-O4 Antibody, clone 81 is an antibody against O4 for use in IC, IH. 主要应用 - Immunohistochemistry
- Immunocytochemistry
不建议的应用 - Western Blotting
应用说明 Immunohistochemistry: 10-20 μg/mL on unfixed, shock frozen tissue.
Immunocytochemistry: 10-20 μg/mL on cells fixed with 4% paraformaldehyde.
Note: O4 is a sulfatide, which can be dissolved out of the membrane by organic solvents; acetone and methanol should not be used for fixation.
Optimal working dilutions must be determined by the end user.
Immunohistochemistry protocol
1. Prepare sections from unfixed, shock frozen tissue. The sections should be 4-5 μm thick. Place the sections on microscope slides.
2. Wash the slide three times for 5 min. each in PBS at room temperature.
3. Block the non-specific binding sites by incubating the sections in a humid chamber with 5% FCS at room temperature for 30 minutes.
4. Wash the slides as described in step 2.
5. Cover the sections with a sufficient amount of MAB345 (10-20 μg/mL in PBS) and incubate in a humid chamber at 37°C for one hour.
6. Wash the slides briefly three times with PBS. Carefully dry around the area to be stained.
7. Cover the sections with a sufficient amount of anti-mouse IgM-fluorescein* solution and incubate in a humid chamber at 37°C for one hour.
8. Wash the slides as described in step 6.
9. Cover the sections with a suitable embedding medium, cover with a cover slip, and examine by fluorescence microscopy.
*HRP or ABC can also be used.
Optimal results can be obtained by titrating the primary and secondary antibodies
Immunocytochemistry
1. Fix the preparations with 4% paraformaldehyde (in PBS) at room temperature for 10 minutes. O4 is a sulfatide which can be dissolved out of the membrane by organic solvents; acetone and methanol should not be used for fixation.
2. Wash the slide three times for 5 min. each in PBS at room temperature.
3. Block the non-specific binding sites by incubating the sections in a human chamber with 5% FCS at room temperature for 30 minutes.
4. Wash the slides as described in step 2.
5. Cover the sections with a sufficient amount of MAB345 (10-20 μg/mL in PBS) and incubate in a humid chamber at 37°C for one hour.
6. Wash the slides briefly three times with PBS. Carefully dry around the area to be stained.
7. Cover the sections with a sufficient amount of anti-mouse IgM-fluorescein solution and incubate in a humid chamber at 37°C for one hour.
8. Wash the slides as described in step 6.
9. Cover the sections with a suitable embedding medium, cover with a cover slip, and examine by fluorescence microscopy.
Note: Do not allow the preparations to dry out during staining.生物信息 免疫原品种 Homogenate of white matter of corpus callosum from bovine brain. 克隆 81 (also referred to in the literature as mAB O4) 浓缩 Varies, see lot specific CoA 宿主 Mouse 特异性 Recognizes Oligodendrocyte marker O4.
