Protein Purification

Protein Purification Description

Depending on the type, size, solubility, tag sequence, expression system, quantity and quality of the protein requested, we combine conventional and FPLC technologies, including affinity chromatograph, anion/cation exchanges, hydrophobic interactions and gel filtration, to guarantee the final protein product with >90% homogeneity. The turn-around time is 1-3 weeks.

To Order Protein Purification

Please click on "Request Quote" link above. Please include the following information in your email:

1. Which expression system wanted (bacterial, baculovirus or mammalian)
2. Which protein (protein name, accession number)
3. Which tag is preferred (6His, Flag, GST, MBP, Biotin etc)
4. Amount of purified protein required (from mg to gram level)
5. Purity of the protein requested (80%, 90% or over 95% homogeneity)
6. Other special requirement (such as endotoxin free or specific buffer condition)

We will evaluate your project and get back to you with quote and project duration.

A standard validation method (protein analysis by SDS PAGE and/or Western blot) is included in our service.
