Product Info
t-Boc-N-Amido-PEG7-propargyl is a crosslinking reagent that enables the formation of triazole linkage with azides under the catalyzation of copper. The Boc-protected amine can be deprotected under mild acidic conditions. By introducing PEG chain into the molecule, the hydrophilicity can be greatly improved. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Available in 3 formats: Mini, Midi, and Maxi to suit your desired input volume
Remove endotoxins from up to 1 mg of DNA with the Maxi format kit
Fast and easy processing using a rapid spin-column format
These kits are designed for the rapid spin column removal of endotoxins from previously purified DNA. Norgen’s spin columns bind DNA while endotoxins, salts and other contaminants are washed away. These kits reduce endotoxins to 0.1 EU/μg DNA or less providing plasmid DNA that is immediately ready for transfections or other endotoxin-sensitive applications. Typical recovery of DNA is >90% of the starting sample.
Endotoxin Removal Kit (Mini)
This kit is designed for the rapid spin column removal of endotoxins from up to 25 µg of previously purified DNA. The convenient spin column procedure can be completed in approximately 20 minutes.
Endotoxin Removal Kit (Midi)
This kit is designed for the rapid spin column removal of endotoxins from up to 200 μg of previously purified DNA. The convenient spin column procedure can be completed in approximately 30 minutes.
Endotoxin Removal Kit (Maxi)
This kit is designed for the rapid spin column removal of endotoxins from up to 1 mg of previously purified DNA. The convenient spin column procedure can be completed in approximately 30 minutes.
About Endotoxins
Endotoxins (also called lipopolysaccharides), are cell-membrane components of Gram-negative bacteria such as E. coli. Endotoxins are released during the lysis step of plasmid purification and significantly reduce transfection efficiencies in endotoxin sensitive cell lines. Therefore, the removal of endotoxins from plasmid preparations is often necessary prior to the use of the DNA in such downstream applications.
Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment.
[CD7000] SMOChem™ dUTP Solution – Sodium Salt (100 mM), 25ml

Product Info
Description
Ultrapure dUTP (2´-Deoxyuridine, 5´-Triphosphate) supplied as sodium salt in purified water (pH 8.5). dUTP can be used in place of dTTP in PCR and RT-PCR protocols to prevent carryover from previous amplifications. The substitution of dUTP for dTTP in PCR results in uracil-containing PCR products that are suitable for most standard applications. The enzyme uracil-N-glycosylase (UNG, also referred to as UDG) can be added to a PCR premix to excise uracil from any contaminating PCR product, thereby preventing false positives. Each lot of dUTP is tested to ensure specific DNA amplification and the absence of nuclease activity.
Features
Ideal for PCR amplification and cDNA synthesis
Nuclease and ribonuclease free
Applications
PCR
Avoid carryover contamination between PCRs to eliminate a source of false positives.
Storage
-20°C for 36 months
