TCO-PEG8-DBCO is a heterobifunctional click chemistry reagent containing a TCO and a DBCO moiety. TCO group specifically and efficiently reacts with terrahydrazine at fast speed. DBCO is very reactive toward Azide through copper free click chemistry, the PEG spacer increases the aqueous solubility of the reagent. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Sequentially purify total RNA and total proteins from a single sample
Kit includes a gDNA elimination column
No sample splitting required
No phenol step required for efficient isolation
Ideal for small or difficult to obtain samples
Purify RNA and proteins from cultured animal cells, tissues, blood, bacteria, yeast, fungi or plants
Rapid and efficient spin column procedure
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
This kit provides a rapid, single column method for the isolation and purification of total RNA (including miRNA) and proteins sequentially from a single sample of cultured animal cells, tissues, blood, bacteria, yeast, fungi or plants. The total RNA and proteins are both column purified in under 25 minutes using a single column.
Purified RNA is of a high quality and yield, and is suitable for NGS, RT-qPCR and microarrays.
This kit eliminates DNA efficiently using a gDNA removal column.
Proteins are eluted in buffer and are ready for downstream applications such as Western Blots, Mass Spec and ELISA. The proteins will not require precipitation, resuspending of pellets, or any further cleaning.
This kit is ideal for researchers who are interested in studying the transcriptome and proteome of a single sample, such as for studies of microRNA profiling, gene expression including gene silencing experiments or mRNA knockdowns, studies involving biomarker discovery, and for characterization of cultured cell lines. Norgen’s RNA/Protein Purification Plus Kit is especially useful for researchers who are isolating macromolecules from precious, difficult to obtain or small samples such as biopsy materials or single foci from cell cultures, as it eliminates the need to fractionate the sample. Furthermore, analysis will be more reliable since the RNA and proteins are derived from the same sample, thereby eliminating inconsistent results. The purified macromolecules are of the highest purity and can be used in a number of different downstream applications.
