How do I make aptamer?
Prior to use, dilute the aptamer to its working concentration in Folding Buffer:1 mM MgCl2, 1X PBS (137 mM NaCl, 2.7 mM Potassium Chloride, 8 mM Sodium Phosphate dibasic, 2 mM Potassium Phos- phate monobasic). Heat the aptamer solution to 85 — 95 ºC for 5 minutes.
Is aptamer DNA or RNA?
Aptamers are short, single-stranded DNA or RNA (ssDNA or ssRNA) molecules that can selectively bind to a specific target, including proteins, peptides, carbohydrates, small molecules, toxins, and even live cells. Aptamers assume a variety of shapes due to their tendency to form helices and single-stranded loops.
How do you build an aptamer?
Aptamers can now be developed using both RNA and DNA, as well as non-natural bases, backbones, and small molecules. Applications include: detection molecules in ELISA-like assays, protein-specific tissue staining, targeted drug delivery, and an FDA-approved treatment for macular degeneration2,3.
What is SELEX used for?
Systematic Evolution of Ligands by EXponential Enrichment (SELEX) is a common method currently used for isolating high-affinity single-stranded (ss) DNAs or RNAs from a large library with random sequences [1,2,3].
How do you dilute an aptamer?
Combine folded aptamer 1:1 (equal volumes) with Aptamer Reducing Buffer. 2. Incubate for 10 minutes at room temperature (20-25°C) 3. The aptamer should now be diluted into the final working buffer, or Application Buffer, containing 1 mM MgCl2 and used immediately.
What is magnesium (antidote) used for?
Magnesium ( antidote) is used to treat digitalis toxicity and hydrofluoric acid burns in adults and hypomagnesemia or torsades de pointes in pediatric patients. What Are Dosages of Magnesium (Antidote)? Indicated for the treatment of documented hypomagnesemia or for torsades de pointes ( polymorphic VT associated with long QT interval)
Does magnesium (antidote) interact with other medications or foods?

Magnesium (antidote) has no listed moderate interactions with other drugs. Magnesium (antidote) has no listed mild interactions with other drugs. This document does not contain all possible interactions.
What is the difference between heparin and pegnivacogin?
Pegnivacogin is a RNA aptamer that blocks factor IX and IXa. An interesting feature is the availability of the complementary RNA aptamer anivamersen that can immediately neutralize the anticoagulant effects of pegnivacogin. Pegnivacogin has shown promising results in phase II dose-ranging studies compared with heparin in patients with ACS [88,89].
