Biotinylation 2D Western Blot

Our Biotinylated Protein 2D Western Blot platform offers high sensitivity detection and accurate quantitation of protein biotinylation in any protein sample. Biotinylation is the process of covalently attaching biotin to a protein. Due to the strong affinity between biotin and streptavidin, the biotinylated proteins have been widely used to study protein-protein interactions.

Example 1: Human lung cancer cells

Proteins from Human lung cancer cells were extracted, followed by Biotinylated Protein 2D Western Blot using Applied Biomics’ protocols. Protein biotinalytion was revealed using CF647-labeled strepavidin (Biotium, Fremont, California).

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.
