1) Trityl monitoring at 3 stages during synthesis for every oligo
2) Every oligo is either HPLC or PAGE analyzed
3) Weekly batch sampling by ion-paired RP-HPLC
4) Weekly in-house PCR tests
5) “QC Recall Program” Our stringent Pre-delivery Quality Controls ensure that all oligos are delivered in excellent condition.

Protein (N-Terminal) Sequencing Proteins samples are electro blotted to polyvinylidenedifluouride (PVDF) and stained with Coomassie Blue R-250 (please do not use Pierce GelCode Blue Stain or other pre-made stains as they may contain detergents, which can interfere with some PTH amino acids). When a large amount of protein (40-100 pmol) is available, running three to five lanes is helpful. Multiple bands can be cut if needed, especially for higher molecular weight proteins. If the amount of protein is limited (10-20 pmol), a single lane may be required to see the bands of interest with Coomassie.
