CD68巨噬細胞（鼠單克隆抗體）

廣州健侖生物科技有限公司

CD68 是一種分子量為110KDa 的糖蛋白，與溶酶體顆粒有關。此抗體可研究人體許多組織中的巨噬細胞，包括脾臟、腸固有層、肺泡和骨髓中的枯否細胞和巨噬細胞，外周血的單核細胞也呈陽性反應，同時也可以研究骨髓前體細胞和外周血粒細胞。近年來有文獻報道，CD68也可以作為組織細胞的標志物。主要用于巨噬細胞方面的研究以及急慢性髓樣白血病和組織細胞來源的腫瘤如惡性纖維組織細胞瘤的研究。

CD68巨噬細胞（鼠單克隆抗體）

經(jīng)Percoll密度梯度離心，細胞主要在相鄰梯度的界面處形成細胞帶。如表2所示，分布在11%～19%Percoll梯度間的主要是細胞間質、細胞碎片及少量死細胞，記為1帶；分布在19%～27%percoll梯度間的細胞較少，平均密度為2.35×105個／ml，記為2帶；分布在27%～35% Percoll梯度間的細胞zui多，平均密度達1.58×106，記為3帶；分布在35%～43% Percoll梯度間的細胞也較少，平均密度為2.68×105，記為4帶。統(tǒng)計學分析顯示，2、3、4帶中細胞分布差異極顯著(P<0.01)，其中3帶與2、4帶之間相比差異極為顯著(P<0.01)，2、4帶之間相比差異不顯著(P>0.05)。
3.分離細胞的形態(tài)學鑒定
電鏡觀察顯示，分離細胞圓形或卵圓形，胞質中除可見有少量具有板層狀嵴的線粒體外其他細胞器不發(fā)達；核質比較大，核大呈圓形，常染色質細密均勻，異染色質少，呈塊狀附著于核膜內面或散在于核內。其形態(tài)結構特征與7～8d小鼠睪丸切片上的精原細胞**(圖1)。
4.精原細胞的分離純度
1帶中主要為死細胞及細胞碎片；2、4帶中細胞接種后，大部分細胞延展后伸出突起，從形態(tài)學判定，主要為支持細胞及少量管周肌樣細胞。主要收集3帶中細胞，接種培養(yǎng)約3～4h，其中的支持細胞開始貼壁而精原細胞尚未貼壁，此時進行精原細胞的純化；純化細胞體外培養(yǎng)約7～8h后，絕大部分支持細胞已貼壁，大部分精原細胞開始貼壁，此時進行細胞計數(shù)。結果如表4所示，3帶中精原細胞的純度平均達到68.76%。

After Percoll density gradient centrifugation, the cells formed cell strands predominantly at adjacent gradient interfaces. As shown in Table 2, interstitial cells, cell debris and a small number of dead cells distributed between 11% and 19% of Percoll gradient were recorded as a band. Fewer cells distributed between 19% and 27% percoll gradients, The average density was 2.35 × 105 cells / ml, which was recorded as 2 bands. The cells distributed in 27% -35% Percoll gradient had the highest average density of 1.58 × 106, which was recorded as 3 bands. The distribution was between 35% and 43% of Percoll gradient Between the cells less, the average density of 2.68 × 105, recorded as 4 band. Statistical analysis showed that there was significant difference in the distribution of cells in 2,3,4 band (P <0.01), among which the difference between 3 band and 2,4 band was extremely significant (P <0.01) Compared with the difference was not significant (P> 0.05).
3. Isolation of cells morphological identification
Electron microscopy showed that the cells isolated round or oval, in addition to the cytoplasm can be seen in a small amount of mitochondria with lamellar ridges other underdeveloped organelles; relatively large nuclear, nuclear large circular, dense chromatin, Heterochromatin less, was attached to the nucleus inside the patch or scattered in the nucleus. The morphological features of the spermatogonia were consistent with the spermatogonia in 7-8 day mouse testis sections (Figure 1).
Separation of spermatogonia purity
1 with dead cells and cell debris in the band; 2,4 cells with inoculation, the majority of cells after the extension of the protruding process, from the morphological determination, mainly for supporting cells and a small amount of tubular muscle-like cells. Mainly collected cells with 3, inoculation culture of about 3 ~ 4h, in which the supporting cells began to adhere to the spermatogonia have not yet attached (Figure 2), then spermatogonia purified; purified cells cultured in vitro about 7 ~ 8h After most of the supporting cells have been adherent, most of the spermatogonia began to attach (Figure 3), at this time for cell counting. As shown in Table 4, the purity of the spermatogonia in the third band reached an average of 68.76%.
