Anwendungsinformationen

Applikationshinweise: Western blot: 1 μg/mL for chemiluminescence detection system. For details see protocol below.

Protokoll: SDS-PAGE & Western Blotting 1) Wash the cells 3 times with PBS and suspend with 10 volume of cold Lysis buffer (50 mM Tris-HCl, pH 7.2, 250 mM NaCl, 0.1 % NP-40, 2 mM EDTA, 10 % glycerol) containing appropriate protease inhibitors. Incubate it at 4 o C with rotating for 30 minutes, then sonicate briefly (up to 10 seconds). 2) Centrifuge the tube at 12,000 x g for 10 minutes at 4 o C and transfer the supernatant to another tube. Measure the protein concentration of the supernatant and add the cold Lysis buffer to make 8 mg/mL solution. 3) Mix the sample with equal volume of Laemmli's sample buffer. 4) Boil the samples for 3 minutes and centrifuge. Load 10 μ L of the sample per lane in a 1 mm thick SDS-polyacrylamide gel for electrophoresis. 5) Blot the protein to a polyvinylidene difluoride (PVDF) membrane at 1 mA/cm 2 for 1 hour in a semi-dry transfer system (Transfer Buffer: 25 mM Tris, 190 mM glycine, 20 % MeOH). See the manufacture's manual for precise transfer procedure. 6) To reduce nonspecific binding, soak the membrane in 5 % skimmed milk (in PBS, pH 7.2) for 1 hour at room temperature, or overnight at 4 o C. 7) Incubate the membrane with primary antibody diluted with PBS, pH 7.2 containing 5 % skimmed milk as suggest in the APPLICATIONS for 1 hour at room temperature. (The concentration of antibody will depend on condition.) 8) Wash the membrane with PBS-T [0.05 % Tween-20 in PBS] (5 minutes x 3 times). 9) Incubate the membrane with the 1:5,000 HRP-conjugated anti-mouse IgG diluted with 5 % skimmed milk (in PBS, pH 7.2) for 1 hour at room temperature. 10) Wash the membrane with PBS-T (10 minutes x 3 times). 11) Wipe excess buffer on the membrane, then incubate it with appropriate chemilumine scence reagent for 1 minute. Remove extra reagent from the membrane by dabbing with paper towel, and seal it in plastic wrap. 12) Expose to an X-ray film in a dark room for 3 minutes. Develop the film as usual. The condition for exposure and development may vary. (Positive controls for Western blotting Jurkat, U937, MOLT4)

Details zu Retinoblastoma 1

Target: Retinoblastoma 1 (RB1)

Andere Bezeichnung: retinoblastoma-associated protein,rb1

Hintergrund: Cyclin-dependent kinases (Cdks) play important roles in the regulation of the cell cycle. RB protein (pRB) is phosphorylated by cyclin D-Cdk4/Cdk6 and cyclin A/cyclin E-Cdk2 during the G 1 /S transition. This phosphorylation causes the inactivation of the growth inhibitory functions of pRB. pRB undergo phosphorylation and attendant functional inactivation, the cell proceed into late G 1. Cyclin D-Cdk4 specifically phosphorylates Ser780 in pRB, while cyclin E-Cdk2 and cyclin A-Cdk2 does not.
