Many researchers are required to purify their biological sample to isolate their protein of interest.  These proteins may need to be isolated in order to further characterize it and use the purified protein in downstream assays to determine the function.  There are many techniques one can use to isolate the protein they are interested in.  The tools that are used for protein purification or protein separation can make a big difference in the resulting purified protein sample.  Ideally, each experiment will have a high yield of the purified protein with very little or no artifacts of other proteins present in the isolated sample.  Also, it’s important for the protein to retain its native confirmation.  The purification technique used should avoid denaturation so all characterization and functional protein studies are valid and accurate.

MBL International is proud to provide tools to meet the various needs of each unique protein that requires purification/separation assays.  The tools we offer are popular among researchers because they are easy to use, maintain native confirmation, and produce high quality and yield of their protein of interest.

Smart IP

Smart IP uses antibodies conjugated to either magnetic beads or magnetic agarose beads to purify your protein.  This highly specific tool for immunoprecipitation results in high yield and is a gentler and faster technique because centrifugation is not required. Simply place your tube in a magnetic rack and watch separation occur.


Epitope Tag

Epitope tag antibodies can be used for purification assays as well as other applications.  MBL International offers many common epitope tag antibodies including HA, HIS, V5 and others.  Our epitope tag antibodies are highly cited and widely trusted among researchers world-wide.



Magnosphere™ magnetic beads are widely trusted due to our high quality and reliable manufacturing process.  Magnosphere™ beads are ensured to have uniform particle size, preventing aggregation.   These beads are offered with different coatings including: Streptavidin, Tosyl, and Carboxyl to meet the protein separation conditions your experiment requires.
