Protocol Id: 10
This protocol is intended for immunoprecipitation of native proteins utilizing Protein A agarose beads for analysis by western immunoblot or kinase activity.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
10X Cell Lysis Buffer: (#9803) To prepare 10 ml of 1X cell lysis buffer, add 1 ml cell lysis buffer to 9 ml dH2O, mix.
NOTE: Add 1 mM PMSF (#8553) immediately prior to use.
IMPORTANT: Appropriate isotype controls are highly recommended in order to show specific binding in your primary antibody immunoprecipitation. Use Normal Rabbit IgG #2729 for rabbit polyclonal primary antibodies, Rabbit (DA1E) mAb IgG XP® Isotype Control #3900 for rabbit monoclonal primary antibodies, Mouse (G3A1) mAb IgG1 Isotype Control #5415 for mouse monoclonal IgG1 primary antibodies, Mouse (E5Y6Q) mAb IgG2a Isotype Control #61656 for mouse monoclonal IgG2a primary antibodies, Mouse (E7Q5L) mAb IgG2b Isotype Control #53484 for mouse monoclonal IgG2b primary antibodies, and Mouse (E1D5H) mAb IgG3 Isotype Control #37988 for mouse monoclonal IgG3 primary antibodies. Isotype controls should be concentration matched and run alongside the primary antibody samples.
Proceed to one of the following specific set of steps.
NOTE: When using primary antibodies produced in rabbit to detect proteins with a molecular weight in the range of 50 kDa, we recommend using Mouse Anti-Rabbit IgG (Light-Chain Specific) (D4W3E) mAb (#45262) or Mouse Anti-Rabbit IgG (Conformation Specific) (L27A9) mAb (#3678) (or HRP conjugate #5127) as a secondary antibody to minimize interference produced by denatured rabbit heavy chain. For proteins with a molecular weight in the range of 25 kDa, Mouse Anti-Rabbit IgG (Conformation Specific) (L27A9) mAb (#3678) (or HRP conjugate #5127) is recommended to minimize interference produced by denatured mouse light chain.
When using primary antibodies produced in mouse to detect proteins with a molecular weight in the range of 50 kDa, we recommend using Rabbit Anti-Mouse IgG (Light Chain Specific) (D3V2A) mAb (HRP Conjugate) (#58802) as a secondary antibody to minimize interference produced by denatured mouse heavy chain.

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.

Protocol Id: 24
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.

通过采用特定于人 FoxO3 蛋白羧基末端的重组蛋白对动物进行免疫接种来产生单克隆抗体。
Forkhead 转录因子家族参与横纹肌肉瘤和急性白血病的发生 (1-3)。这个家族中,三个成员(FoxO1、FoxO4、 FoxO3a)与线虫的同源基因 DAF-16 具有序列相似度,而 DAF-16 信号转导包括 IGFR1,PI3K 和 Akt 在内的信号通路 (4-6)。活化的 forkhead 成员作为抑癌基因,促进细胞周期阻滞和凋亡。FoxO 家族任何成员的表达上调,均会激活细胞周期抑制剂 p27 Kip1。Forkhead 转录因子也参与 TGF-β 介导的 p21 Cip1 上调,而这个上调过程可以被 PI3K 负调控 (7)。Forkhead 转录因子通过 Akt 在 Thr24、Ser256 和 Ser319 位点的磷酸化灭活时,增殖增加,导致出核和转录因子活性受到抑制 (8)。Forkhead 转录因子还可被 deacetylase sirtuin (SirT1) 抑制 (9)。
