DBCO-S-S-acid is a cleavable reagent for introduction of a carboxylic acid moiety to azide-containing biomolecules using copper-free Click Chemistry. PEG spacer arm provides better solubility to the labeled molecules in aqueous media. The disulfide bond in this linker can be cleaved using reducing agents such as DTT, BME and TCEP.

Product Info
DBCO-PEG4-Desthiobiotin is a PEG linker containing a desthiobiotin group and a DBCO functional group. Desthiobiotin is used for affinity-based applications such as pull-down assays or for ligating with streptavidin proteins while DBCO is a click chemistry handle that quickly reacts with azide groups on target molecules. Desthiobiotin is a sulfur-free analogue of biotin which binds streptavidin with slightly less strength than biotin, which provides it with a soft-release characteristic that is useful for in pull-down assays by minimizing co-elution with endogenous biotinylated molecules. The inclusion of a PEG linker in this molecule improves its aqueous solubility.

The kit offers the unique feature to isolate total RNA including small RNA and DNA from serum and plasma without the need to resort to the cumbersome phenol/chloroform extraction or a time consuming proteinase digest. RNA purified using the kit is ready for applications such as RT-PCR, Northern blotting, poly A+ RNA (mRNA) purification, nuclease protection, and in vitro translation.

Principle
HiPure RNA technology simplifies total RNA isolation. The sample material is denatured in Lysis Buffer. The protein is then precipitated by Protein Precipitation Solution and pelleted by centrifugation. After the removal of protein the binding conditions for nucleic acids are adjusted by adding isopropanol. Total nucleic acids are bound to the column. Optionally, DNA can be removed by an on-column DNase digest. The remaining nucleic acids are washed and eluted with minimal amounts of RNase-Free water.
