的两个病毒巨噬细胞炎症蛋白(vMIP)-I, -II, 我们有病理组织,已经通过PCR验证了病理组织中确实存在两个蛋白,现在要通过免疫组化来显示病理组织中存在的(vMIP)-I, -II,搜到文献一篇,但是本人因为没有做过免疫组化,所以对于文献提供的信息看不懂,下面有几个疑问帮忙解答一下
1.文章中没有直接提到vMIP)-I, -II抗体名字,是否两个蛋白的抗体可以直接找试剂公司找和买到。
2.本人也了解了一下免疫组化步骤,主要涉及到1抗和2抗,文中的2抗是否就是anti-rabbit IgG ,而我做的是人标本,是否可以用?
3,文中开始介绍了一段“Briefly, BC-3 cells (107 cells) in RPMI medium were induced with 20 ng/ml TPA (Sigma).
The cells were collected after 48 h of exposure to TPA, washed in phosphate-buffered saline
(PBS), pH 7.4, and spotted on slides in circles with 5-mm inner diameters, 24 circles per slide.”这段文字介绍的是什么?一般免疫组化准备好病理片子后,开始脱蜡水化,难道它说的步骤代替了脱蜡水化步骤吗?我们的组织都在病理蜡块里面。
4,哪位是这方面高手啊,可以直接指点我一下吗,我的QQ12607718,万分感谢。
Briefly, BC-3 cells (107 cells) in RPMI medium were induced with 20 ng/ml TPA (Sigma).
The cells were collected after 48 h of exposure to TPA, washed in phosphate-buffered saline
(PBS), pH 7.4, and spotted on slides in circles with 5-mm inner diameters, 24 circles per slide.
The slides were air-dried, then fixed in cold acetone for 10 min. The cells were then washed
with washing buffer (PBS supplemented with 0.1% Triton X-100) for 15 min, and incubated
with anti-vMIP-I or anti-vMIP-II monospecific antibodies (diluted 1:100 in IFA dilution
buffer [PBS containing 2% bovine serum albumin, 0.2% Tween-20, and 0.05% NaN2 ]) for
1 h at 37 ◦ C. After incubation, the slides were washed with washing buffer, then incubated
for 1 h at room temperature with a prestandardized dilution of rhodamine-conjugated goat
anti-rabbit IgG (Tago Immunologicals, Camarillo, CA). After washing, the slides were stained
with Hoechst 33342 to detect nuclei and mounted with 50% (v/v) glycerol in PBS. Three-
dimensional data sets were collected using a Deltavision microscope (Applied Precision,
Issaquah, WA), based on a Carl Zeiss inverted microscope with a Photometrics PXL cooled
CCD camera. The data sets were deconvolved, projected onto a single plane, and the contrast
was adjusted before the images were exported as TIFF files to Adobe Photoshop. |
