B. Deparaffinization/Rehydration

NOTE: Do not allow slides to dry at any time during this procedure.

  1. Deparaffinize/hydrate sections:
    1. Incubate sections in three washes of xylene for 5 minutes each.
    2. Incubate sections in two washes of 100% ethanol for 10 minutes each.
    3. Incubate sections in two washes of 95% ethanol for 10 minutes each.
  2. Wash sections twice in dH2O for 5 minutes each.

  2. D. Staining

    1. Wash sections in dH2O three times for 5 minutes each.
    2. Incubate sections in 1X TBST for 5 min.
    3. Block each section with 100-400 µl of preferred blocking solution for 1 hour at room temperature.

    TrueBlack® Lipofuscin Autofluorescence Quencher protocol

    Following Section D Step 6:

    IMPORTANT: TrueBlack® Lipofuscin Autofluorescence Quencher is not compatible with detergent. Any steps involving detergent must be done before applying TrueBlack® Lipofuscin Autofluorescence Quencher.

    1. Prepare TrueBlack® Lipofuscin Autofluorescence Quencher solution by diluting 1:20 in 70% ethanol. Vortex to mix.
      NOTE: Quenching solution should be made fresh prior to use and discarded if precipitate is visible. We recommend heating the vial of stock solution of TrueBlack® Lipofuscin Autofluorescence Quencher, 20X in DMF to 70°C prior to dilution in order to avoid precipitate formation.
    2. Immediately cover tissue sections with 100 µL - 200 µL of quenching solution for 30 seconds at room temperature.
      IMPORTANT: Do not allow sections to dry out. Sections may tolerate longer incubations (up to 3 minutes) so long as they remain hydrated.
    3. Tap slides on an absorbent towel to collect excess TrueBlack® Lipofuscin Autofluorescence Quencher before transferring to 1X PBS.
    4. Rinse three times in 1X PBS for 5 min each.

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

Iba1/AIF-1 (E4O4W) XP® Rabbit mAb (Alexa Fluor® 647 Conjugate) 可识别内源水平的 Iba1/AIF-1 总蛋白。

物种反应性:

人, 小鼠, 大鼠, 仓鼠 , 猴

来源/纯化

使用与人 Iba1/AIF-1 蛋白 Ala139 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

离子钙结合适配器分子 1 (IBA1),也称为同种异体移植炎症因子 1 (AIF-1),是一种进化上保守的细胞浆钙结合蛋白,包含一对 EF-HAND 钙结合基序(1,2)。Iba1/AIF-1最初是从经历慢性移植排斥的人动脉粥样硬化同种异体心脏移植物中的活化巨噬细胞以及大鼠单核细胞(3,4)克隆的。它的功能还不是很清楚,但是 Iba1/AIF-1 的表达由于干扰素-γ 的表达而上调,因此可以调节巨噬细胞依赖性免疫应答(3)。作为 F-肌动蛋白结合蛋白,Iba1/AIF-1 可能起着重塑肌动蛋白细胞骨架的作用,并促进与各种小胶质细胞/巨噬细胞状态相关的形态变化(5)。Iba1/AIF-1 在单核细胞系细胞中也表达独特,因此被广泛用作大脑和其他组织中的小胶质细胞/巨噬细胞的标记物(6)。
