Product Info
Introduction
The Kit provides fast purification of high-quality RNA from paxigene Blood RNA Tube using silica-membrane spin columns. RNA purified using the HiPure System is ready for applications such as RT-PCR, Northern blotting, poly A+ RNA (mRNA) purification, nuclease protection, and in vitro translation.
The Kit is for the purification of total RNA from 2.5 ml human whole blood collected in a PAXgene Blood RNA Tube. Purification begins with a centrifugation step to pellet nucleic acids in the PAXgene Blood RNA Tube. The pellet is washed and resuspended, and incubated in optimized buffers together with proteinase K. DNA wash The lysate is passed through a DNA Mini column. Ethanolis added to adjust binding conditions, and the lysate is applied to a column.RNA is selectively bound to the silica membrane as contaminants pass through. Remaining contaminants are removed in several efficient wash steps. Between the first and second wash steps, the membrane is treated with DNase I to remove trace amounts of bound DNA. After the wash steps, RNA is eluted in elution buffer and heat-denatured.
Advantages
High quality – high purity total RNA can be directly used in various sensitive downstream applications
Fast – isolation of several samples can be completed in 40 minutes by using column purification method
Safety – no phenol chloroform extraction required
Sensitive – direct lysis of blood, plasma and other samples without separation of leukocytes

Storage and Stability
Proteinase K should be stored at 2–8°C upon arrival. DNase I should be stored at -20°C. However, short-term storage (DNase I up to 1 weeks, Proteinase K up to 8 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under these conditions.

TCO-PEG24-DBCO is a monodisperse, long PEG linker featuring a trans-cyclooctene and a DBCO group. DBCO easily reacts with azides through click chemistry, while the TCO group readily reacts with tetrazine-containing compounds.

Cytokeratin 19 (CK19) forms intermediate filaments found in the intracytoplasmic cytoskeleton of epithelial tissue and provides mechanical support. Anti-Cytokeratin 19 stains epithelia and epithelial malignancies such as carcinomas of the colon, stomach, pancreas, biliary tract, liver, and breast. Cytokeratin 19 is a useful marker for distinguishing hepatocellular carcinoma from intrahepatic cholangiocarcinoma. This differentiation is improved when stained in combination with Cytokeratin 7, CAM5.2l, Ber-EP4/MOC31, HepPar1 and TTF1. Cytokeratin 19 staining can also be used to recognize thyroid papillary carcinomas.
