Western blot analysis of FOS using anti-FOS antibody (M00297).
Electrophoresis was performed on a 10% SDS-PAGE gel at 80V (Stacking gel) / 120V (Resolving gel) for 2 hours. The sample well of each lane was loaded with 30 ug of sample under reducing conditions.
Lane 1: human Hela whole cell lysates,
Lane 2: human RT4 whole cell lysates.
After electrophoresis, proteins were transferred to a nitrocellulose membrane at 150 mA for 50-90 minutes. Blocked the membrane with 5% non-fat milk/TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-FOS antigen affinity purified monoclonal antibody (M00297) at 1:500 overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal is developed using an ECL Plus Western Blotting Substrate (Catalog # AR1196-200) with Tanon 5200 system. A specific band was detected for FOS at approximately 41 kDa. The expected band size for FOS is at 41 kDa.

IF analysis of c-Fos using anti-c-Fos antibody (M00297).
c-Fos was detected in an immunocytochemical section of mouse brain tissue. Enzyme antigen retrieval was performed using IHC enzyme antigen retrieval reagent (AR0022) for 15 mins. The cells were blocked with 10% goat serum. And then incubated with 1:200 rabbit anti-c-Fos Antibody (M00297) overnight at 4°C. DyLight®594 Conjugated Goat Anti-Rabbit IgG (BA1142) was used as secondary antibody at 1:500 dilution and incubated for 45 minutes at 37°C. The section was counterstained with DAPI. Visualize using a fluorescence microscope and filter sets appropriate for the label used.

2 Reviews For Anti-c-Fos Rabbit Monoclonal Antibody
The Anti-c-FOS antibody (M00297) showed clear and specific immunofluorescence staining in mouse brain, with markedly increased c-Fos expression in neurons of the acute ischemic region compared to normal brain.
Excellent

| SKU | M00297 |
|---|---|
| Application | Immunocytochemistry |
| Sample | mouse brain |
| Sample Processing Description | Normal brain tissue and brain tissue from a cerebral infarction model |
| Other Reagents | Goat serum, DAB Chromogenic Solution, Anti-fade mounting medium |
| Primary Antibody | c-Fos Rabbit Monoclonal Antibody |
| Primary Incubation | 1:200, overnight at 4 ℃ |
| Secondary Antibody | DyLight 594 Goat Anti-Rabbit IgG (H+L) |
| Secondary Incubation | 45 min at 37℃ |
| Detection | Imaging system:Leica DM2500 |
| Results Summary | c-Fos is a marker of activated neural cells, especially neurons. During the acute phase of cerebral infarction, as a strong stress and injury stimulus, it drives c-Fos expression in the brain—particularly in the peri-infarct region—far higher than in normal resting brain. The experimental results show clear staining of positive cells, and the expression levels are consistent with expectations. |

|---|---|
| Application | Western Blot |
| Sample | Mouse hippocampal tissue |
| Sample Processing Description | An Alzheimer’s disease (AD) model was established by injecting streptozotocin (STZ) into the lateral ventricles of mice. Hippocampal tissues were collected after treatment with four different doses of QianCengTa compound, and total protein was extracted. |
| Other Reagents | RIPA lysis buffer,Protease inhibitor,Electrophoresis buffer,Transfer buffer,Blocking buffer |
| Primary Antibody | c-Fos Rabbit Monoclonal Antibody |
| Primary Incubation | 1:2000, overnight at 4 ℃ |
| Secondary Antibody | HRP Goat Anti-Rabbit IgG |
| Secondary Incubation | 1:10000, 1 hour in room temperature |
| Detection | Substrate: ECL, Imaging system:ChemiDoc MP |
| Results Summary | c-FOS is a marker of neuronal activation under pathological conditions. Its expression is low in normal brain tissue but elevated in the AD model, and decreases following drug treatment. Lane 1 represents normal hippocampus, lane 2 the AD model hippocampus, lanes 3, 4, and 5 correspond to increasing doses of QianCengTa compound, and lane 6 is the positive control drug. The Western blot results indicate that QianCengTa compound exhibits a therapeutic effect on AD. |

Question
We are currently using anti-c-Fos Rabbit Monoclonal antibody M00297 for rat tissue, and we are content with the WB results. The species of reactivity given in the datasheet says human, mouse, rat. Is it likely that the antibody can work on pig tissues as well?
K. Taylor
Verified customer
Asked: 2015-12-28
Answer
The anti-c-Fos Rabbit Monoclonal antibody (M00297) has not been validated for cross reactivity specifically with pig tissues, but there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in pig you can get your next antibody for free. Please contact me if I can help you with anything.
