Optimal dilution of the p27 antibody to be determined by the researcher.
1. Staining of formalin-fixed tissues requires boiling tissue sections in 10 mM Citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 min
2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.\. Flow Cytometry: 0.5-1 μg/million cells in 0.1ml,Immunofluorescence: 0.5-1 μg/mL,Western blot: 0.5-1 μg/mL,Immunohistochemistry (FFPE): 0.25-0.5 μg/mL for 30 min at RT (1),Prediluted format : incubate for 30 min at RT (2) - 限制

- Denature total cellular lysates proteins in 1x SDS-sample buffer and separate proteins on a freshly cast denaturing 10% SDS-PAGE (Laemmli, 1970).
- Transfer proteins onto 0.2µm Protran membrane (GE Healthcare, 10600004, A10043108) with a Western blotting system for 1h at 400A (Towbin et al., 1979).
- Block the membrane in TBST (50mM Tris-HCl, pH7.4, 150mM NaCl, 0.2% Tween 20) containing 5% milk (blocking solution) for 60min at RT.
- Incubate membrane with primary mouse anti-P27 antibody (antibodies-online, ABIN3025539, lot V2438-171009) diluted 1:250 in blocking solution ON at 4°C.
- Incubate membrane with secondary anti-mouse IgG (whole molecule), HRP-linked (Sigma-Aldrich, A9044, lot 034M4761) diluted 1:5000 in TBST for 45min at RT.
- Wash membrane with TBST for 30-45min at RT.
- Reveal protein bands using Clarity Max Western ECL substrate (Bio-Rad, 1705062); image capture via Chemidoc Imaging System (BioRad).
- Experimental Notes
ABIN3025539 reveals a protein band at the expected molecular weight of the mVenus-p27 fusion protein. The antibody does also detect a protein at the expected molecular weight of the endogenous, untagged p27.
生效 #101901 (Western Blotting)Validation ImagesDifferent volumes of total cellular lysates of either mVenus-p27K- transfected NIH/3T3 cells (1, 2, 3) or untransfected NIH/3T3 cells (4, 5) were loaded and the blot membrane was incubated with ABIN3025539 followed by incubation with anti-mouse IgG-linked to HRP and chemiluminescence detection. Expected molecular weight of p27 fused to mVenus is approximately 55kDa.

- 背景
- Recognizes a 27 kDa protein, identified as the p27Kip1, a cell cycle regulatory mitotic inhibitor. Its epitope spans between aa 83-204 of p27. It is highly specific and shows no cross-reaction with other related mitotic inhibitors. p27Kip1 functions as a negative regulator of G1 progression and has been proposed to function as a possible mediator of TGF- induced G1 arrest. p27Kip1 is a candidate tumor suppressor gene. This mAb co-precipitates cdk4 in complex p27Kip1 and is excellent for staining of formalin-fixed tissues.
