Alkyne-PEG2-iodide is a crosslinker containing a propargyl group and an iodine group. The propargyl group can form triazole linkage with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry reactions. Iodine (I) is a very good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research use only.

Attogene’s Carbon Dioxide Enzymatic Assay Kit is a simple, direct method for measuring Carbon Dioxide levels in the environment. The assay uses a coupled enzyme assay to detect CO2 (as HCO3-) as follows. In the first step, the bicarbonate condenses with phosphoenol pyruvate to form oxalate (and phosphoric acid); this reaction is catalyzed by the enzyme Phosphoenolpyruvate Decarboxylase, PEPC. The oxalate is then enzymatically reduced by the enzyme Malate Dehydrogenase (using an NADH cofactor) to form malate and NAD+.
Heat-Labile Exonuclease I (HL-ExoI) is a 3’ – 5’ exonuclease, specific for single stranded DNA. The enzyme is recombinantly produced in E. coli. HL-ExoI is active at 25 – 37°C and inactivated by 1 minute incubation at 80°C or 15 minutes at 60°C.
HL-ExoI is used for degradation of ssDNA such as primers and oligos. It is also ideal for treatment of sensitive samples and useful in the development of novel molecular diagnostics applications.
