Scientific Data Images for DEC1 Antibody - BSA Free

Western Blot: DEC1 Antibody - BSA Free [NB100-1800] - Western Blot Image of anti-DEC1. Whole cell protein from A431 (lane 1) and PC3 (lane 2) was separated on a 12% gel by SDS-PAGE, transferred to PVDF membrane and blocked in 5% non-fat milk in TBST. The membrane was probed with 2 ug/ml anti-DEC1 in 1% milk, and detected with an anti-rabbit HRP secondary antibody using chemiluminescence.
Immunocytochemistry/Immunofluorescence: DEC1 Antibody - BSA Free [NB100-1800] - HeLa cells were fixed for 10 minutes using 10% formalin and then permeabilized for 5 minutes using 1X TBS + 0.5% Triton-X100. The cells were incubated with anti-DEC1 (NB100-1800) at a 1:200 dilution overnight at 4C and detected with and anti-rabbit Dylight 488 (Green) at a 1:500 dilution. Alpha tubulin was used as a co-stain at a 1:1000 dilution and detected with and anti-mouse Dylight 550 (Red) at a 1:500 dilution. Nuclei were counterstained with DAPI (Blue). Cells were imaged using a 40X objective.
Immunohistochemistry: DEC1 Antibody - BSA Free [NB100-1800] - Immunohistochemical detection of DEC1 in myocardial and stromal cells. Representative images of one WT heart treated with TAC and sham at four weeks. The black square shows representative large images, magnification 400x.

Background: DEC1

The basic helix-loop-helix (bHLH) transcription factor DEC1 (differentially expressed in chondrocytes protein 1) is wildly expressed in most normal tissues in a proportion of cells, whereas in tumors, its expression gets upregulated (potentially by hypoxia) in several malignancies such as breast, stomach, colon, lung, liver cancer and pancreatic ductal adenocarcinoma. The gene expression of DEC1 is regulated by various extracellular stimuli in a cell type-specific manner. Localized in the nucleus, it can homodimerize or heterodimerize with TCF3/E47, and interacts with ubiquitin-conjugating enzyme UBE2I/UBC9. DEC1 has emerged as one of the major circadian molecules alongwith its involvement in homeostasis of metabolism and energy. DEC1 has been shown to play a key role in various biological phenomena such as circadian rhythms, neurogenesis, neuroregulation, chondrogenesis, cellular growth, carcinogenesis, immune response balance as well as cellular senescence.

[[URL:]][[Caption:D… Antibody]]
Culture cells to appropriate density in 35 mm culture dishes or 6-well plates.

1. Remove culture medium and add 10% formalin to the dish. Fix at room temperature for 30 minutes.
2. Remove the formalin and add ice cold methanol. Incubate for 5-10 minutes.
3. Remove methanol and add washing solution (i.e. PBS). Be sure to not let the specimen dry out. Wash three times for 10 minutes.
4. To block nonspecific antibody binding incubate in 10% normal goat serum from 1 hour to overnight at room temperature.
5. Add primary antibody at appropriate dilution and incubate at room temperature from 2 hours to overnight at room temperature.
6. Remove primary antibody and replace with washing solution. Wash three times for 10 minutes.
7. Add secondary antibody at appropriate dilution. Incubate for 1 hour at room temperature.
8. Remove antibody and replace with wash solution, then wash for 10 minutes. Add Hoechst 33258 to wash solution at 1:25,0000 and incubate for 10 minutes. Wash a third time for 10 minutes.
9. Cells can be viewed directly after washing. The plates can also be stored in PBS containing Azide covered in Parafilm (TM). Cells can also be cover-slipped using Fluoromount, with appropriate sealing.

Western Blot Protocol

1. Perform SDS-PAGE on samples to be analyzed, loading 25 ug of total protein per lane.
2. Transfer proteins to membrane according to the instructions provided by the manufacturer of the membrane and transfer apparatus.
3. Stain according to standard Ponceau S procedure (or similar product) to assess transfer success, and mark molecular weight standards where appropriate.
4. Rinse the blot.
5. Block the membrane using standard blocking buffer for at least 1 hour.
6. Wash the membrane in wash buffer three times for 10 minutes each.
7. Dilute anti-DEC1 primary antibody in blocking buffer and incubate 1 hour at room temperature.
8. Wash the membrane in wash buffer three times for 10 minutes each.
9. Apply the diluted HRP conjugated secondary antibody in blocking buffer (as per manufacturers instructions) and incubate 1 hour at room temperature.
10. Wash the blot in wash buffer three times for 10 minutes each (this step can be repeated as required to reduce background).
11. Apply the detection reagent of choice in accordance with the manufacturers instructions.
Note: Tween-20 can be added to the blocking or antibody dilution buffer at a final concentration of 0.05-0.2%.
