Flow Cytometry, Methanol Permeabilization Protocol for Directly Conjugated Antibodies

A. Solutions and Reagents

All reagents required for this protocol may be efficiently purchased together in our Intracellular Flow Cytometry Kit (Methanol) #13593, or individually using the catalog numbers listed below.

NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.

  1. 1X Phosphate Buffered Saline (PBS): To prepare 1 L 1X PBS: add 100 ml 10X PBS (#12528) to 900 ml water mix.
  2. 4% Formaldehyde, Methanol-Free (#47746)
  3. 100% Methanol (#13604): Chill before use
  4. Antibody Dilution Buffer: Purchase ready-to-use Flow Cytometry Antibody Dilution Buffer (#13616), or prepare a 0.5% BSA PBS buffer by dissolving 0.5 g Bovine Serum Albumin (BSA) (#9998) in 100 ml 1X PBS. Store at 4°C.

NOTE: When including fluorescent cellular dyes in your experiment (including viability dyes, DNA dyes, etc.), please refer to the dye product page for the recommended protocol. Visit www.cellsignal.com for a full listing of cellular dyes validated for use in flow cytometry.

B. Fixation

NOTE: Adherent cells or tissue should be dissociated and in single-cell suspension prior to fixation.

NOTE: Optimal centrifugation conditions will vary depending upon cell type and reagent volume. Generally, 150-300g for 1-5 minutes will be sufficient to pellet the cells.

NOTE: If using whole blood, lyse red blood cells and wash by centrifugation prior to fixation.

NOTE: Antibodies targeting CD markers or other extracellular proteins may be added prior to fixation if the epitope is disrupted by formaldehyde and/or methanol. The antibodies will remain bound to the target of interest during the fixation and permeabilization process. However, note that some fluorophores (including PE and APC) are damaged by methanol and thus should not be added prior to permeabilization. Conduct a small-scale experiment if you are unsure.

  1. Pellet cells by centrifugation and remove supernatant.
  2. Resuspend cells in approximately 100 µl 4% formaldehyde per 1 million cells. Mix well to dissociate pellet and prevent cross-linking of individual cells.
  3. Fix for 15 min at room temperature (20-25°C).
  4. Wash by centrifugation with excess 1X PBS. Discard supernatant in appropriate waste container. Resuspend cells in 0.5-1 ml 1X PBS. Proceed to Permeabilization step.
    1. Alternatively, cells may be stored overnight at 4°C in 1X PBS.

C. Permeabilization

  1. Permeabilize cells by adding ice-cold 100% methanol slowly to pre-chilled cells, while gently vortexing, to a final concentration of 90% methanol.
  2. Permeabilize for a minimum of 10 min on ice.
  3. Proceed with immunostaining (Section D) or store cells at -20°C in 90% methanol.

D. Immunostaining

NOTE: Count cells using a hemocytometer or alternative method.

  1. Aliquot desired number of cells into tubes or wells. (Generally, 5x105 to 1x106 cells per assay.)
  2. Wash cells by centrifugation in excess 1X PBS to remove methanol. Discard supernatant in appropriate waste container. Repeat if necessary.
  3. Resuspend cells in 100 µl of diluted primary antibody, prepared in Antibody Dilution Buffer at a recommended dilution or as determined via titration.
  4. Incubate for 1 hr at room temperature. Protect from light.
  5. Wash by centrifugation in Antibody Dilution Buffer or 1X PBS. Discard supernatant. Repeat.
  6. Resuspend cells in 200-500 µl of 1X PBS and analyze on flow cytometer.

特异性/灵敏度

N-Myc (D4F9Z) Rabbit mAb 可识别内源水平的 N-Myc 总蛋白。

物种反应性:

来源/纯化

使用与人 N-Myc 蛋白 Pro335 周围残基相对应的合成肽,对动物进行免疫接种来产生单克隆抗体。

背景

Myc/Max/Mad 网络成员可作为转录调节分子,在增殖、分化和凋亡等多种细胞行为方面发挥作用 (1)。这些蛋白质均有一个共同的基础螺旋-环-螺旋亮氨酸拉链 (bHLH-ZIP) 基序,这是二聚化和 DNA 结合所需的。Max 最初是因其与 c-Myc 的相互作用能力而被发现,并发现其为 Myc 蛋白与 DNA 结合和激活转录过程所必需 (2)。随后,Max 一直被视为转录网络的核心组分,并与 Myc 和 Mad 家族其他成员形成同型二聚体和异二聚体 (1)。Max 与 Myc 或 Mad 的相互作用对转录调控和细胞行为可能有相反的作用 (1)。Mad 家族包括四个相关的蛋白质;Mad1、Mad2 (Mxi1)、Mad3 和 Mad4,以及 bHLH-ZIP 家族最不相关的成员 Mnt 和 Mga。与 Myc 一样,Mad 蛋白由短半衰期严格调控。在一般情况下,Mad 家族成员通过抑制转录干扰 Myc 蛋白介导的过程,如增殖、转录和抑制细胞凋亡 (3,4)。
