Celebrate Memorial Day with Proteos

As Memorial Day approaches, Proteos would like to extend our warmest wishes to you and your loved ones for a safe and enjoyable weekend.

Methods for Determining Aggregation

Methods for Determining Aggregation

SDS-PAGE and analytical HPLC-SEC are valuable methods for detecting protein aggregation.

Considerations for Minimizing Aggregation

Considerations for Minimizing Aggregation

Previously, the importance of protein solubility during the production process was discussed. Here we continue with considerations that can improve protein solubility and reduce aggregation.

Protein Solubility and Aggregation

Protein Solubility and Aggregation

Solubility is an important consideration at any stage of recombinant protein production.

Fusion Proteins for Mammalian Cell Expression

Fusion Protein Removal Following Mammalian Cell Expression

Fusion proteins are often used to increase the expression and solubility of the target protein but may negatively affect the functionality of the target protein in biochemical or structural studies.

Proteos stands ready to help you complete your 2022 discovery research goals before the end of the year.

Fusion Protein Placement for Mammalian Cell Expression

Fusion Protein Placement for Mammalian Cell Expression

The design and placement of a fusion protein partner relative to the protein of interest must be critically considered and empirically tested since it can significantly affect protein expression and function.

Selecting a Fusion Protein for Mammalian Cell Expression

Selecting a Fusion Protein for Mammalian Cell Expression

Our transient mammalian cell expression system can be used to produce functional fusion proteins with extended in vivo half-life for use in pre-clinical proof of concept (POC) studies, through selection of an appropriate fusion partner.

Fusion Proteins for Mammalian Cell Expression

Fusion Proteins for Mammalian Cell Expression

There are many variables to consider when producing novel recombinant proteins. These variables include selection of an expression system, construct design, and scale. In the upcoming months, we will focus on the use of fusion proteins for recombinant protein expression in mammalian cell systems including purpose, selection, placement, and removal.
