產品信息
【好消息】:應客戶的要求,我司對試劑盒內的Diluent C可單獨供應,產品信息如下:
產品描述 PKH67細胞連接試劑盒(用于常規細胞膜標記)(PKH67 Cell Linker Kit for General Cell Membrane Labeling)是一款基于熒光探針PKH67,用于常規細胞膜標記的檢測試劑盒,適用于體外細胞標記,體外細胞增殖以及長期的體內細胞跟蹤研究等。
PKH67是一種專利的膜標記探針,與PKH1和PKH2相比,結構上帶有更長的脂肪族碳尾,能穩定插入細胞膜脂質區域。正因具更長碳尾,內部數據連續性證明:PKH67具有比PKH2更低的細胞-細胞間轉運發生。PKH67呈綠色熒光(見圖1),最大激發波長為490nm,最大發射波長是502nm,與標準熒光素(Fluorescein)濾片兼容。PKH67非常適合用于細胞毒性實驗,與碘化丙啶(PI,MX4205)或7-氨基放線菌素D(7-AAD,MX4215)這些細胞活力探針聯合使用,或者與橙-紅色熒光探針比如藻紅蛋白(PE,MX4698)、紅色熒光蛋白(RFP)等結合使用。根據染料稀釋原理,PKH67常用于細胞增殖監測分析,包括抗原特異性的前體頻率和帶干細胞特性的靜息/緩慢分化腫瘤細胞的鑒定。也能用于監測外泌體或脂質體吞噬,細胞-細胞膜轉運、吞噬、抗原遞呈,以及體內細胞運輸研究。
以不分裂細胞為研究對象,通過對體外細胞膜滯留周期和體內熒光強度減弱頻率的關聯性分析,預測PKH67的體內熒光半衰期為10-12天。這與PKH1和PKH2的體內半衰期相近,這兩個探針都成功用于監測周期長達1-2個月的體內淋巴細胞和巨噬細胞運輸研究,因此,PKH67適用于需要綠色熒光細胞連接染料的短-中期體內示蹤研究,以及體外細胞毒性、吞噬、增殖、抗原遞呈,或其它共培養實驗。
稀釋液C(Diluent C)是本試劑盒配套提供的一種水溶性溶液,特別設計的一種標記媒介能維持細胞活力,同時最大化染料溶解性和標記過程中的染色效率。Diluent C對哺乳動物細胞來說是等滲的,不含去污劑或有機溶劑,也不含生理鹽和緩沖劑。根據細胞類型,染料標記后膜的內在化程度,標記細胞可能呈現不同的狀態,從明亮,到均勻點狀或斑駁狀。然而,PKH67熒光在生理范圍內不依賴于pH,且每個細胞的熒光強度通常不受染料位置的影響。

我司(懋康生物)提供三種規格的PKH67細胞連接試劑盒(用于常規細胞膜標記),其中: Mini Kit(CAT#:MX4023-100UL)建議用于小量或初步研究。當使用2ml染色體積(含2μM終濃度的PKH67),本試劑盒含有足量的染料用于檢測25次細胞樣本(2×107個細胞/次),和足量的Diluent C用于5次細胞樣本(2×107個細胞/次)。用戶需根據細胞類型和實驗目的來優化確定最佳的染料濃度。 Midi Kit(CAT#:MX4023-200UL)適用于中量研究,比如體外細胞增殖或毒性研究。當使用2ml染色體積(含2μM終濃度的PKH67),本試劑盒含有足量的染料用于檢測50次細胞樣本(2×107個細胞/次),和足量的Diluent C用于30次細胞樣本(2×107個細胞/次)。用戶需根據細胞類型和實驗目的來優化確定最佳的染料濃度。 Maxi Kit(CAT#:MX4021-500UL)適用于大量或體內研究。當使用2ml染色體積(含2μM終濃度的PKH67),本試劑盒含有足量的染料用于檢測125次細胞樣本(2×107個細胞/次),和足量的Diluent C用于30次細胞樣本(2×107個細胞/次)。用戶需根據細胞類型和實驗目的來優化確定最佳的染料濃度。

PKH67 staining assay
Exosome uptake of EJ and T24 cells was analyzed by PKH67 staining assay using the kit according to the manual (MX4023-100UL; Shanghai Maokang Biotech Co., Ltd.). Briefly, 2 × 107 exosomes were collected and resuspended in 1 ml Diluent C. 4 μl of PKH67 solution was added into the resuspension and incubated for 5 min. Then, the PKH67-labeled exosomes were incubated with EJ and T24 cells for 24 h and the cellular location of the exosomes was observed by a fluorescence microscope. DAPI was used to stain the nuclei of the tumor cells.

In Vitro Macrophage Phagocytosis Assay
PBMC, immortalized Bone Marrow-Derived Macrophage (iBMDM) cells, or THP-1 cells activated with PMA (#S1819, Beyotime, 100 ng mL?1 for three days) were labeled with PKH26 (#MX4021, MaokangBio), while cancer cells were labeled with PKH67 (#MX4023, MaokangBio), following the manufacturer's instructions. The macrophages were then mixed with the cancer cells at a ratio of 2:1 and seeded onto a 6-well plate. Images were taken at the indicated time points, and the phagocytic index was calculated as the number of phagocytosed cancer cells per 100 macrophages. For anti-CD47 antibody treatment, 10 μg mL?1 anti-CD47 antibody or isotype IgG was added to the co-culture medium of CHX2000 cells and iBMDM cells at a 1:1 cell ratio. Cancer cell confluence was determined by fluorescent imaging and quantification.
