DBCO-PEG4-Butyraldehyde is a click chemistry PEG reagent containing a terminal butylraldehyde group. Butyraldehyde reacts with hydrazide to form a stable hydrazone linkage or with alkoxyamines to form a stable oxime bond. The hydrophilic PEG spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research use only.

Adenoviral vectors are useful tools for both in vitro and in vivo gene transfer, and oncolytic viruses based on adenovirus are highly promising for cancer treatment. Norgen’s Adenovirus Purification Kit provides a fast and simple procedure for concentrating and purifying adenoviral vectors from cell lysate and cell culture media. Purification is based on spin column chromatography using Norgen’s proprietary resin as an ion exchanger. Contaminating cellular debris is largely removed from the sample via a centrifugation step, while contaminating DNA and RNA is reduced using enzymatic digestion. Adenoviral vectors purified in this manner are highly active for use in transduction experiments.
Norgen’s Adenovirus Purification Kit contains sufficient materials for 15 preparations (33.5 mL per prep of supernatant or a total of 500 mL of supernatant input). Approximately 1 mL of cell pellet can be purified per prep, up to a maximum of 15 mL of cell pellet in total for the entire kit.

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+.
t-Boc-N-Amido-PEG9-propargyl is an alkyne linker that can be used in Click Chemistry reactions with azides to yield a stable triazole linkage; copper is required for catalyzation. Under mild acidic conditions, the Boc group can be removed to form a free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
