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+.
The 16S ribosomal RNA (rRNA) plays a crucial role in bacterial and archaeal ribosomes. This sequence is Highly conserved across bacteria and archaea, it contains variable regions useful for species differentiation and is part of the 30S subunit of prokaryotic ribosomes. 16s rRNA Binds to the Shine-Dalgarno sequence and contributes to the subunit’s structure. Acts as a scaffold for ribosomal proteins.
Because the 16s rRNA sequence is ubiquitous in bacteria and archaea, it can be used to identify a wide diversity of microbes within a single sample and single workflow.
