We offer different types of purification for the customized applications,as well as standard RAPD Kits for the researcher's demand.
●  Desalt,
Catridge purification is extremely precise technology method based on the reverse phase chromotography. Oligos are quantitated by UV spectrophotometry/Nano-Drop Technology to provide an accurate measure of yield in Optical density (OD). This varies with length and decreases for shorter oligos. All oligos are quality controlled (QC) and checked by Mass spectrometry.
Xcelris offers HPLC Purification for Modified & Unmodified oligos for an advanced technology with RP-HPLC in high resolution & high intensity due to chromatographic separation for the cloning application. With this technology we can separate n-x & most truncated sequence created during synthesis, thus increasing better productivity.
Xcelris offers unique PAGE purification for longer oligonucleotides ,which requires highest level of purification for the most sensible reactions. In PAGE technique, it removes most truncated failures during synthesis, and achieves 95% purity, better than any other purification method.
