    Answer

    Thank you for contacting us. We do not know of any publications using ab67102 or ab108938. The protocol used with ab67102 is below: Blocking buffer (also Dilution buffer) Weigh non-fat milk 5 g and dissolve in 100 mL 1X PBST (0.2%) to a final mixture of 5% non-fat milk/PBST (0.2%).  (10X) PBST (phosphate buffer saline) NaCl (0.13 M x 10, Merck 6404) 75.9 g NaH2PO4·H2O (0.01 M x 10, Merck A429146 335) 13.8 g Add 800 mL ddH2O. After the salts have dissolved, use NaOH liquid to adjust the solution to pH 7.0 and make the final dilute solution to 1,000 mL. The solution becomes 10X PBS. Dilute the solution with ddH2O to the final 1X PBS prior application. PBST (0.2%) (Phosphate buffer saline and 0.2% Tween 20) 1X PBS 1 L Tween 20 2 mL Dilute 10X PBS with ddH2O to a final 1X concentration. Add Tween 20 [0.2% (v/v)] to final PBST (0.2%).   Anti-IgG Secondary antibody Goat Anti-Mouse IgG (H&L)-HRP Conjugate secondary antibody  Chemiluminescent reagent SuperSignal® West Femto Maximum Sensitivity Substrate (PIERCE, Cat. No. 34094, 34095 & 34096) Reagent must be freshly prepared each time before application. Add adequate amount of blocking buffer and incubate the membrane at room temperature for 1 hour or under 4°C overnight. Dilute the primary antibody with fresh blocking buffer to the designated concentration (1/500). Remove the membrane from the previous blocking buffer and add the diluted primary antibodies to the membrane. Incubate at 4°C overnight. Wash membrane with PBST (0.2%) for 10 minutes. Repeat 3 times. Add adequate amount of anti-IgG secondary antibody. Leave the membrane at room temperature for 1 hour. Wash membrane with PBST (0.2%) for 10 minutes. Repeat 4 times. After washing, place membrane into a sealable bag and add freshly prepared chemiluminescent reagents into the bag to coat the entire membrane. For maximum sensitivity, PIERCE SuperSignal® West Femto Maximum sensitivity substrate is recommended. The reagent should be in 1:1 dilution of reagent A and B as working solution (Strictly follow the provider's instructions). Add working solution to the membrane and seal the bag. Spread the chemiluminescent reagent around so it can be distributed evenly onto the membrane. (Chemiluminescent reagent must be spread out evenly otherwise parts of the membrane will be over-exposed when the photograph is taken.) 0.6 mL of working solution is used for membrane size 8 cm x 10 cm. Take photographs immediately with CCD camera at 5-second, 20-second, 1.5-minute, and 5-minute intervals, in order to acquire proper exposure image.  Strong signals may intensify into blackout signals with hollow band. In this case, dilute the secondary antibody. The protocol for ab52193 is below: 1. Solutions and Reagents 1.1. 10X Cell Lysis Buffer RIPA buffer (Radio Immuno Precipitation Assay buffer) 150 mM sodium chloride 1.0% NP-40 or Triton X-100 0.5% sodium deoxycholate 0.1% SDS (sodium dodecyl sulphate) 50 mM Tris, pH 8.0 - Add Phenylmethylsulfonyl fluoride (PMSF) toCEll Lysis Buffer to a final concentration of 1mM. (Stock solution 100mM PMSF) NOTE : Add fresh before each use - Add protease and phosphatase inhibitors. - 1X protease inhibitor mixture consists of 2 mM AEBSF, 1 mM EDTA, 130 μM bestatin, 14 μM E-64, and 0.3 μM aprotinin. 1.2. 2X Laemmli Sample Buffer: 62.5 mM Tris-HCl (pH 6.8), 25% glycerol, 2% SDS, 0.01% Bromophenol Blue, 710 mM beta-mercaptoethanol 1.3. TBST (50 mM Tris, pH 7.6, 150 mM NaCl, 0.1% Tween-20) TBST is Tris Base Saline buffer with 0.1% Tween-20 1.5. 5% bovine serum albumin (BSA): Use 25 g in 500 ml TBST 1.6. Goat anti-rabbit HRP antibody 1.7. Chemiluminesence reagents; such as ECL materials and film or imaging system for detection 2. Cell Lysis and Western Blotting Protocol Westerns are performed using cell lysates from harvested cells. 2.1. Adherent cells 2.1.1 Grow cells to ~90% confluency. 2.1.2 Wash cells twice with TBS to remove media 2.1.3 Add the appropriate volume of 1x Cell lysis buffer (ex: 3ml to a T175 flask) 2.1.4 Transfer cell lysates to Eppendorf tubes and sonicate for 10-15 seconds. 2.1.5 Spin at 14,000 rpm, 4 °C for 10 minutes. 2.2. Suspension cells 2.2.1 Pipette cells gently into a conical tube and centrifuge 10 min. at 1000 rpm 2.2.2 Wash cells twice with TBS 2.2.3 Add the appropriate volume of 1x Cell lysis buffer and transfer to Eppendorf tubes (ex: 1ml for 1X10 7 cells) 2.2.4 Sonicate for 10-15 seconds. 2.2.5 Spin at 14,000 rpm, 4 °C for 10 minutes. 2.3. Remove a small volume (50 ul) to perform a protein assay. Determine the protein concentration for each cell lysate. 2.4. To the remaining volume of cell lysate, add an equal volume of 2X Laemmli Sample Buffer (final concentration of 1 mg/ml). 2.5. Boil each cell lysate in sample buffer at 100 °C for 5 min and aliquot. Use a 26-gauge needle to shear released chromatin. Store lysates at -20 °C. Note: Aliquot cell lysates (50-100 μl) in order to avoid repeat freeze/thaw cycles. 2.6. Defrost tubes containing cell lysate at 37 °C. Centrifuge at 14,000 rpm in a microcentrifuge for 5 min. 2.7. Load equal amounts (10-20 μg) cell lysate onto SDS-PAGE gels using gel loading tips, along with molecular weight markers. 2.8. Run gels and transfer for western blotting. 3. Western Blotting 3.1. Block nitrocellulose for 1 hour at room temperature or overnight at 4°C using 5% BSA or 5%. 3.2.Incubate nitrocellulose with appropriate dilutions of primary antibody in 5% BSA overnight at 4°C or for 2 hours at room temperature 3.3. Wash nitrocellulose with three 5-min washes using TBST. 3.4.Incubate nitrocellulose with goat anti-rabbit HRP antibody, diluted to 1:500 to 100,000 in 5% BSA, for 1-2 hours at room temperature. 3.5. Wash nitrocellulose in 3 washes of TBST, then rinse in TBS prior to addition of chemiluminesence reagents. 3.6. Remove excess chemiluminescence reagent and sandwich nitrocellulose blot in any type of transparent plastic wrap (plastic cling wrap, transparent sheet protector, etc.). 3.7. Acquire image using darkroom development techniques. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
