产品概述

荧光染料Hoechst 33258是一种可对DNA染色的细胞核染色试剂,也称bisBenzimide H 33258或HOE 33258,常用于细胞凋亡检测。

Hoechst 33258是一种可以穿透细胞膜的蓝色荧光染料,对细胞的毒性较低。

Hoechst染料可透过细胞膜并对DNA染色而发出强烈的蓝色荧光。它们在聚AT序列的富集区域的小沟处与DNA结合。Hoechst 33258和Hoechst 33342均可溶于水并在水溶液中保持稳定。Hoechst-DNA的激发和发射波长分别为350 nm和460 nm。

原理

Cellstain- Hoechst 33258 solution细胞核染色试剂货号:H341

操作说明

染色步骤

1.用PBS或适当的缓冲液制备10-50μMHoechst染料溶液。a)

2.在细胞培养基中加入体积为细胞培养基1/10的Hoechst染料溶液。b)

3.将细胞在37ºC下孵育10-20分钟。

4.用PBS或适当的缓冲液清洗细胞两次。

5.在带有350 nm激发和460 nm发射滤光片的荧光显微镜下观察细胞。

a)由于赫斯特染料可能具有致癌性,因此在处理过程中必须格外小心。

b)或者您可以用1/10浓度的Hoechst染料缓冲溶液代替培养基。

DNA Stain[1]

体外研究
(In Vitro)

Hoechst 33342 binds to adenine-thymine-rich regions of DNA in the minor groove. On binding to DNA, the fluorescence greatly increases. This protocol describes the use of Hoechst 33342 to label nuclear DNA of cells grown in culture. Hoechst 33342 can also be used to stain fixed cells by substituting Hoechst 33342 for DAPI[1].

生物活性

Hoechst 33258 is a fluorescent dye that emits blue fluorescence when bound to dsDNA.

IC50 Target

IC50: 51.31±4.56 μM (HeLa cell), 32.43±3.27 μM (HL60 cell), 15.42 ± 2.16 μM (U937 cell)[1]

体外研究
(In Vitro)

Hoechst 33258, a fluorescent compound with a head-to-tail bis-benzimidazole structure, is initially found to be cytotoxic against L1210 murine leukemia. Hoechst 33258 is evaluated for their cytotoxicity against human tumor cell lines, which are cervix carcinoma cell line (HeLa), Human promyelocytic leukemia cell (HL60) and U937 cell Line. The IC50 determined in the case of HeLa, HL60 and U937 is 51.31±4.56, 32.43±3.27 and 15.42±2.16 μM for Hoechst 33258, respectively[1]. The cytotoxic property of Hoechst 33258 is investigated on a panel of seven tumour cell lines of different histological origin and Madine-Darby canine kidney (MDCK) normal cells. All cell lines, except MCF-7, exposed to Hoechst 33258 exhibit GI50 from 84×10-6 to 191.5×10-6 mol/dm3. Under the same experimental conditions, Hoechst 33258, used as a binder reference compound, stops the cell cycle in S phase and G0/G1[2].

Cell Assay
[2]

Hoechst 33258 is prepared as stock solutions in highly pure water. Working solutions in a concentration range of 10-3-10-6 mol/dm3 are prepared prior to testing. Cytotoxic effects of Hoechst 33258 on tested cell lines are determined by the MTT assay. Cells are seeded in 96 micro well flat bottom plates at a concentration of 2×104 cells/mL and left overnight in the CO2 incubator allowing them to attach to the plate surface. Growing medium is replaced with compound supplemented or control medium and incubated for 72 h. Fresh medium with 5 mg/mL of MTT is added onto cells and incubated for 4 h at 37°C. Upon media removal, water insoluble MTT-formazan crystals formed inside the living cells are dissolved in DMSO and the absorbance at 570 nm proportional to the number of living cells is measured on an Elisa Microplate Reader. All experiments are performed at least three times in triplicates.The GI50 value, defined as the compound concentration (μM) leading to cellular growth inhibition by 50%, is calculated and used as a parameter to compare cytotoxicity among the compounds[2].

Hoechst 33258 trihydrochloride is a fluorescent dyes, which can be used as a cell dye for DNA.

IC50 Target

IC50: 51.31±4.56 μM (HeLa cell), 32.43±3.27 μM (HL60 cell), 15.42±2.16 μM (U937 cell)[1]

体外研究
(In Vitro)

Hoechst 33258, a fluorescent compound with a head-to-tail bis-benzimidazole structure, is initially found to be cytotoxic against L1210 murine leukemia. Hoechst 33258 is evaluated for their cytotoxicity against human tumor cell lines, which are cervix carcinoma cell line (HeLa), Human promyelocytic leukemia cell (HL60) and U937 cell Line. The IC50 determined in the case of HeLa, HL60 and U937 is 51.31±4.56, 32.43±3.27 and 15.42±2.16 μM for Hoechst 33258, respectively[1]. The cytotoxic property of Hoechst 33258 is investigated on a panel of seven tumour cell lines of different histological origin and Madine-Darby canine kidney (MDCK) normal cells. All cell lines, except MCF-7, exposed to Hoechst 33258 exhibit GI50 from 84×10-6 to 191.5×10-6 mol/dm3. Under the same experimental conditions, Hoechst 33258, used as a binder reference compound, stops the cell cycle in S phase and G0/G1[2].

生物活性

Hoechst 33258 analog 3 are part of a family of blue fluorescent dyes used to stain DNA. IC50 Value: Target: These Bis-benzimides were originally developed by Hoechst AG, which numbered all their compounds so that the dye Hoechst 33342 is the 33342nd compound made by the company. There are three related Hoechst stains: Hoechst 33258, Hoechst 33342, and Hoechst 34580. The dyes Hoechst 33258 and Hoechst 33342 are the ones most commonly used and they have similarexcitation/emission spectra. Both dyes are excited by ultraviolet light at around 350 nm, and both emit blue/cyan fluorescent light around anemission maximum at 461 nm. Unbound dye has its maximum fluorescence emission in the 510-540 nm range. Hoechst dyes are soluble in water and in organic solvents such as dimethyl formamide or dimethyl sulfoxide. Concentrations can be achieved of up to 10 mg/mL. Aqueous solutions are stable at 2-6 °C for at least six months when protected from light. For long-term storage the solutions are instead frozen at ≤-20 °C. The dyes bind to the minor groove of double-stranded DNA with a preference for sequences rich in adenine andthymine. Although the dyes can bind to all nucleic acids, AT-rich double-stranded DNA strands enhance fluorescence considerably. Hoechst dyes are cell-permeable and can bind to DNA in live or fixed cells. Therefore, these stains are often called supravital, which means that cells survive a treatment with these compounds. Cells that express specific ATP-binding cassette transporter proteins can also actively transport these stains out of their cytoplasm.
