Product Review: RUVBL1 antibody – N-terminal region (ARP32349_P050) in K562 lysate using Western Blot

Product Page for RUVBL1 antibody – N-terminal region (ARP32349_P050)

Researcher: Sustackova Gabriela
Application: Western Blotting
Species+tissue/cell type: Lane 1: 30ug K562 lysate
Primary antibody dilution:1:200
Secondary antibody: Anti-rabbit-HRP
Secondary antibody dilution: 1:1000

Questionnaire:
How do Aviva’s reagents play a role in your experimental goals? I wanted to find antibody which would work for Drosophila cells
Have you used another antibody which has worked in your application? Yes
Do you believe the information about the reagent on Aviva’s website is correct? Yes
How did you store the antibody after re-suspension? In aliquots at -20°C
Sample Description (please include 1) species type, and 2) cell/tissue type, and 3) how much protein loaded for each lane of your gel): 1) Drosophila, 2) Drosophila S2 cells, 3) 30 μg
How many different experimental trials were conducted using the antibody sample? 7
How was this sample prepared? Cells were lysed by sample buffer (50 mM Tris, 10% glycerol, 1% SDS), then sonicated and boiled with 2-mercaptoethanol and bromophenol blue, storage at -20°C
Primary antibody dilution and incubation time: 1:200 in 5% milk, incubated either overnight at 4°C or 1h at room temperature
Secondary antibody used and dilution and incubation time: Goat anti-rabbit conjugated with HRP, incubated for 1h at room temperature
What controls were used in your experiment (positive/negative)? Positive control – K562 cells/ negative control – knockdown of gene in Drosophila cells using dsRNA
Please include your detailed WB Procedure/Protocol here: Samples ran in 12% SDS-polyacrylamide gel at 100-130V. Proteins were transferred from gel to membrane in 1h 30min at 300mA. Blocking – 1h at room temperature in 5% milk. Incubation with RUVBL1 antibody – either overnight at 4°C or 1h at room temperature. Dilution 1:200 in 5% milk. Washing – 3x 10 minutes in PBST buffer (0.05%). Incubation with secondary antibody – 1h at room temperature. Dilution of goat-anti-rabbit – HRP antibody 1:1000 in 5% milk. Washing – 3x 10 minutes in PBST (0.05%). Developed by Clarity Western ECL substrate (Biorad) and exposed to film.
comment to the image:
line 1 – K562 positive control
line 2 – S2 cells control
line 3 – S2 cells with silenced RUVBL1
RUVBL1 should show band around 50 kDa, however in S2 cells there wasn’t any band about this size even with high concentration of antibody and loading of 30 μg of protein sample. In K562 leukemic cells there was a band above 55 kDa (MW marker PageRuler Plus Prestained Protein Ladder, Thermo Scientific).
