Description

The maltose-binding periplasmic protein (MBP), encoded by the malE gene in Escherichia coli, serves as one of the most widely utilized fusion tags in recombinant protein expression systems. Beyond its native role in maltose and maltodextrin transport, MBP has become invaluable as a solubility-enhancing fusion partner that promotes proper folding of difficult-to-express proteins while simultaneously enabling straightforward affinity purification via amylose resin chromatography. For researchers working with MBP-tagged constructs, reliable detection of the fusion partner is essential for monitoring expression levels, confirming purification success, and troubleshooting protein production workflows.

This recombinant monoclonal antibody, derived from clone 10F2, offers the reproducibility that MBP fusion protein work demands. Because the antibody sequence is defined and produced recombinantly in rabbit, you can expect consistent performance across experiments and over time, eliminating the lot-to-lot variability that can complicate longitudinal studies or protocol optimization. The antibody was raised against a synthesized peptide derived from E. coli malE, ensuring specificity for your tagged proteins.

Validation in Western blot applications demonstrates clean detection of the target at the expected 44 kDa molecular weight in E. coli lysates, with effective working dilutions ranging from 1:1000 to 1:5000. This flexibility allows you to optimize signal intensity based on your expression levels and detection system. The antibody is also validated for ELISA, expanding its utility across different experimental approaches.

Whether you are characterizing novel MBP fusion constructs, optimizing expression conditions, or verifying purification efficiency, this antibody provides a dependable tool for your protein production and analysis workflows.

Target Background

Function
Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Binds maltose and higher maltodextrins such as maltotriose.
Gene References into Functions
  1. Upon refolding, MBP initially collapses into a dynamic molten globule-like ensemble, then forms an obligatory on-pathway native-like folding intermediate that brings together sequentially remote segments and then folds globally after a long delay. PMID: 29295923
  2. Our current understanding of what makes MBP such an effective solubility enhancer for other proteins and how it facilitates the proper folding of its fusion partners is presented [REVIEW] PMID: 28132493
  3. Maltose Binding Protein is key to the coupling of maltose transport to ATP hydrolysis in vivo, because it facilitates the progression of the MalK dimer from the open to the semi-open conformation, from which it can proceed to hydrolyze ATP PMID: 26268698
  4. activates mouse macrophages and polarizes them into M1 macrophages PMID: 24825603
  5. a salt-bridge motif in the maltose-binding protein has a role in the initial steps of substrate transport PMID: 16143635
  6. Our findings indicate that the solubility-enhancing activity of MBP is mediated by its open conformation and point to a likely role for the ligand-binding cleft in the mechanism of solubility enhancement. PMID: 17964542
  7. These data indicate that unfolding of the mature domain of preMBP is likely not a rate-determining step in translocation when the protein is targeted to the translocase via SecB. PMID: 18241889
  8. tat mutants are able to transport maltose in the absence of malE. PMID: 18385983
