PhosphoProtein 2D Western Blot: Detect & Quantify
Our PhosphoProtein 2D Western Blot platform offers high sensitivity detection and accurate quantitation of protein phosphorylation in any protein sample. Customers can choose to detect and quantitate a specific type of Protein Phosphorylation such as pSer or pThr or pTyr. In addition, we offer mass spectrometry service to identify the Protein Phosphorylation sites. Applied Biomics’ 2D Fluorescent Western Blot has been successfully applied in studying Kinase/Phosphatase substrate and other functions of Phospho-Proteins.
Example 1. Anti-Phospho-Tyrosine (pTyr) Western Blot
Jurkat cells were treated with serum starvation for 1 hour. Then serum was added to the medium and cultured for 4 hours. Proteins were extracted by 2D lysis buffer following Applied Biomics protocols. First, sample was run on 2D DIGE (pH4-7) and the gel image was scanned using Typhoon 9400 (A). Second, proteins were transferred to the membrane and Western Blot was performed using mouse monoclonal anti-phosphotyrosine antibody (Clone PY20) and CF488-labeled goat anti-mouse Ig (Biotium, Hayward, California). The Western Blot image was scanned using Typhoon 9400 (B).
A. Cell Lysate Total Protein
B. Anti-pTyr Western Blot
C. Total Protein / Anti-pTyr
Example 2. Anti-Phospho-Serine (pSer) Western Blot
Hela cells were treated with 1 mM sodium orthovanadate for 30 minutes. Proteins were extracted by 2D lysis buffer following Applied Biomics protocols. First, sample was run on 2D DIGE (pH4-7) and the gel image was scanned using Typhoon 9400 (A). Western Blot was performed using mouse monoclonal anti-phosphoserine antibody (Sigma) and CF488-labeled goat anti-mouse Ig (Biotium, Hayward, California). The Western Blot image was scanned using Typhoon 9400 (B).
A. Cell Lysate Total Protein
B. Anti-pSer Western Blot
C. Total Protein / Anti-pSer
Example 3. Anti-Phospho-Serine/Threonine/Tyrosine (pSer/pThr/pTyr) Western Blot
Hela cells were treated with 1 mM sodium orthovanadate for 30 minutes. Proteins were extracted by 2D lysis buffer following Applied Biomics protocols. First, sample was run on 2D DIGE (pH4-7) and the gel image was scanned using Typhoon 9400 (A). Western Blot was performed using mouse monoclonal antibodies against pSer/pTyr/pThr (Sigma) and CF488-labeled goat anti-mouse Ig (Biotium, Hayward, California). The Western Blot image was scanned using Typhoon 9400 (B).
A. Cell Lysate Total Protein
B. Anti-pSer/pThr/pTyr Western
C. Protein / Anti-pSer/pThr/pTyr
Sample Info
Please follow these general principles regarding biohazardous materials and buffer condition in getting your samples ready.
Protein amount for each WB: 100-500 µg of total protein from each sample.
Protein concentration: 5-20 mg/ml is preferred.
Primary antibody requirement for each WB: Sufficient for 100ml incubation volume, and need information on:
- Animal species in which the antibody was raised
- Suggested dilution factor
If you cannot provide the dilution factor, please let us know:
- If it is a commercial antibody, provide the link to the antibody information
- If it is not a commercial antibody, please provide the protein concentration of the antibody, whether it is IgG fraction or anti-sera or antigen-affinity purified.
Buffer: Please feel free to submit samples in whichever buffer that you would normally use. The standard sample preparation is covered by the DIGE gel cost. Such samples should have protein concentration in the range of 5-20 mg/ml. Additional charge may apply on samples that require extensive amount of the extra work such as protein eluting, concentrating, buffer exchange or serum abundant protein depletion.
Sample type: Please inform our scientists about your sample type. We will send you additional tips for each sample type.
