Protein Modification and Labeling Services

KMD Bioscience is always up to date with the latest technology in recombinant antibody and protein production. We offer unrivaled expertise in the research of protein modification and detection. Combined with an extensive background in biopharmaceutical and proprietary development platforms, KMD Bioscience can provide comprehensive protein modification and detection services based on the understanding of every client's needs. Up to you, protein purification, GST fusion protein purification, protein sequencing, protein labeling, protein PEGylation and endotoxin testing are available to be chosen.


Protein Purification Services:


Protein purification is vital for the characterization of the function, structure and interactions of the target protein. KMD Bioscience understands that research is a battle against time. That is why we propose a solution to purify your proteins faster. KMD Bioscience pursues cost-effective and customizable services and provides professional scientific support every step of the way, making every penny you spend count. Protein purification services including natural and recombinant protein purification and more are provided to back your research. KMD Bioscience delivers proteins with >90% purity to meet your subsequent experimental needs.


GST Fusion Protein Purification Services:


GST fusion protein has been widely used in recombinant protein expression and production. GST folds rapidly into a stable and highly soluble protein upon translation, so the inclusion of the GST tag often promotes greater expression and solubility of recombinant proteins than expression without the tag. GST-tagged fusion proteins can also be purified or detected based on the ability of GST to bind its substrate, glutathione (GSH).


Protein Sequencing Services:


KMD Bioscience has established a comprehensive protein sequencing platform to meet your individual needs, including N-terminal sequencing and de novo sequencing. Advantages of N-terminal Edman sequencing include high sensitivity, even with picomoles of protein. Proteins can be sequenced in solution, gels or on PVDF blots. If a protein sequence is different from what's available in the protein sequence databases, de novo sequencing is the only way to get a 100% accurate result.


Protein Labeling Services:


Since its foundation, KMD Bioscience has never ceased its pursuit of advanced technology. To date, KMD Bioscience has developed a series of protein labeling techniques covering a wide range of labels, including enzyme conjugation, fluorescent labeling, isotope labeling, PEG labeling, biotinylation, magnetic beads conjugation, and quantum dots labeling. Personalized solutions are designed to supply researchers with selectable choices to meet your research needs.


Protein PEGylation Services:


PEGylation refers to adding polyethylene glycol (PEG) polymer chains onto target molecules to monitor their physiochemical properties. In many cases, protein PEGylation not only significantly improves the physicochemical properties, but also modify the pharmacokinetics and pharmacodynamics of a biosimilar. KMD Bioscience provides custom PEGylated conjugates and PEGylation services for proteins, peptides, oligonucleotides, and small molecules.


Endotoxin Testing Services:


We provide endotoxin testing services for clients by the kinetic turbidimetric method. As the concentration of insoluble coagulin increases during the LAL reaction, the turbidity of the reaction mixture increases. We can also provide a gel-clot method for the detection of endotoxin levels in samples. KMD Bioscience brings together a highly professional team of scientists who can help improve the compliance and efficiency of your endotoxin testing program and gain controllability, consistency and precision.
