N Labeling of Proteins and Peptides

Stable isotope labeled protein and peptide are essential for NMR and Mass in biological studies.
Preparation of such samples are time consuming and labor intensive and sometimes difficult to be done
in a regular biochemical laboratory. This is particular the case for samples with site-specific labeled,
fragment labeled or partial labeled isotopes. EZBiolab provides services for preparation of labeled
protein or peptide samples.

Protein Labeling
Guaranteed at least one NMR sample (0.5 mM in 0.5 ml volume)
.
As part of our highly regarded protein expression and purification services, our custom production of
15N/13C labeled proteins offers full ranges of services from gene synthesis, gene cloning to the final
sample preparation. In addition to uniform labeling, we also offer fragment labeling and site-specific
labeling that allow detailed studies of structure and function of a protein.

Delivery: at least one NMR sample at requested purity or higher. If final yield is more, we will send all of
them to you.

Site specific Labeling and fragment labeling
.
We developed a technology allowing to label a residue in a very specific manner. There is absolutely no
cross labeling to other residues. Only the desired site will be labeled. Please email us your protein for
evaluation and quote.
