NOTE: Please refer to primary antibody product webpage for recommended antibody dilution.
From sample preparation to detection, the reagents you need for your Western Blot are now in one convenient kit: #12957 Western Blotting Application Solutions Kit
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
Load 20 µl onto SDS-PAGE gel (10 cm x 10 cm).
NOTE: Loading of prestained molecular weight markers (#59329, 10 µl/lane) to verify electrotransfer and biotinylated protein ladder (#7727, 10 µl/lane) to determine molecular weights are recommended.
NOTE: Volumes are for 10 cm x 10 cm (100 cm2) of membrane; for different sized membranes, adjust volumes accordingly.
* Avoid repeated exposure to skin.

NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
NOTE: Do not allow slides to dry at any time during this procedure.
For Citrate: Heat slides in a microwave submersed in 1X citrate unmasking solution until boiling is initiated; follow with 10 min at a sub-boiling temperature (95°-98°C). Cool slides on bench top for 30 min.

Protocol Id: 283
Achieve higher quality immunofluorescent images using the efficient and cost-effective, pre-made reagents in our #12727 Immunofluorescence Application Solutions Kit
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
Recommended Fluorochrome-conjugated Anti-Rabbit secondary antibodies:
NOTE: Cells should be grown, treated, fixed and stained directly in multi-well plates, chamber slides or on coverslips.
Aspirate liquid, then cover cells to a depth of 2–3 mm with 4% formaldehyde diluted in 1X PBS.
NOTE: Formaldehyde is toxic, use only in a fume hood.
NOTE: All subsequent incubations should be carried out at room temperature unless otherwise noted in a humid light-tight box or covered dish/plate to prevent drying and fluorochrome fading.

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.
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.
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.
NOTE: Count cells using a hemocytometer or alternative method.

使用与人 AMPKβ1 His233 残基周围序列相对应的合成肽,对动物进行免疫接种来产生单克隆抗体。
AMP 激活的蛋白激酶 (AMPK) 从酵母到植物和动物中都高度保守,且在调节能量平衡方面发挥关键作用 (1)。AMPK 蛋白以一种异三聚体复合体的形式存在,由一个 α-催化亚基、一个 β-调节亚基和一个 γ-调节亚基组成,每个亚基被两到三个不同基因编码 (α1、2;β1、2;γ1、2、3) (2)。该激酶会被因细胞和环境压力引起AMP/ ATP 比值升高而激活,如热休克,缺氧和缺血 (1)。抑癌基因 LKB1 与辅助蛋白 STRAD 和 MO25 一同将位于活化环里 Thr172 位点的 AMPKα 磷酸化,该位点的磷酸化是 AMPK 激酶活性所必需的 (3-5)。AMPKα 在 Thr258 位点和 Ser485 位点(对于 α1;α2 是 Ser491 位点)也被磷酸化。上游激酶以及这些磷酸化事件的生物学意义尚未被阐明 (6)。β1 亚基是通过豆蔻酰化和多位点磷酸化翻译后修饰的,这些位点包括 Ser24/25 位点、Ser96 位点、Ser101 位点、Ser108 位点和 Ser182 位点 (6,7)。β1 亚基 Ser108 位点的磷酸化似乎对 AMPK 酶活性是必要的,而 Ser24/25 位点和 Ser182 位点的磷酸化会影响 AMPK 定位 (7)。已确定了一些 AMPKγ 亚基的突变,其中大部分位于假定的 AMP/ ATP 结合位点(CBS 或Bateman域)。这些位点的突变导致 AMPK 活性降低,引起心脏或骨骼肌糖原积累 (1,2)。越来越多证据表明,AMPK 不仅调节脂肪酸和糖原的代谢,也通过 EF2 和 TSC2/mTOR 通路调节蛋白质合成和细胞生长,另外还通过 eNOS / nNOS 调节血流量 (1)。AMPKβ1 和 AMPKβ2 约有 70% 的序列同源性。这两种同工型对 AMPK 活性起着相同作用。AMPKβ1 主要在肝脏和脑中表达,在肾脏和骨骼肌中的表达水平最低。相比之下,AMPKβ2 在骨骼肌中高表达,在肾脏、肝脏和肺中表达水平较低。
