Western Blotting
Western Blotting Service
Proteometech performs your western blotting experiments on any type of biological material with antibodies and proteins that you supply or with ones that we have.
Assay Development
We provide extensive experience in the development of diagnostic assays. Our scientific team has comprehensive knowledge in developing sensitive assays for various virus or disease markers that include HBV, HCV, HIV, malaria, and allergy.
Enzyme-Linked ImmunoSorbent Assay (ELISA) is frequently used for protein purification, stability or lot release test. We can develop your ELISA assay using polyclonal or monoclonal antibodies. We will consult with you about your final use for the ELISA assay and discuss various formats that can be designed into your assay method. We provide contract ELISA development service that is adapted for direct ELISA, indirect ELISA or sandwich ELISA.
1. Specific assay(s) are developed to your specifications.
2. Technology transfers to the client upon project completion.
3. Cost and timeframe are dependent on the complexity of the project and level of our involvement.
