Product Specification

SEQUENCE:	5’-tttagggttagggttagggttaggg-3’ (lower case letters indicate phosphorothioate linkage).
MW:	8288 (ammonium salt)
SOURCE/HOST:	Synthetic.
QUANTITY:	24nmol (~200µg). Sufficient for ~50 cellular inhibition assays. Working concentration depends upon concentration, type and MW of stimulating human CpG ODN, the cellular system and read-out used. Titrate at 3-10-fold molar excess for inhibition.
PURITY DETAIL:	Endotoxin tested - TLRgrade™.
FORMULATION:	Lyophilized. Sterile.
ENDOTOXIN CONTENT:	<0.002EU/µg (LAL test; BioWhittaker)
RECONSTITUTION:	For a 100µM stock solution, dissolve the total vial content in 240µl endotoxin-free water (included) or PBS (to order separately). To obtain optimal dissolving we recommend the following procedure: - Add 50% of the solvent and let dissolve for 10 min. - Add remaining 50% of the solvent and mix thoroughly. - Moderate warming may aid dissolving.
SHIPPING:	AMBIENT
LONG TERM STORAGE:	+4°C
USE/STABILITY:	Aqueous stock solution is stable for 1 day when stored at +4°C.
HANDLING:	After reconstitution, prepare aliquots and store at -20°C. For maximum product recovery after thawing, centrifuge the vial before opening the cap. Protect from light.
