Matched Pair- Total RNA

BioChain’s Matched Pair Total RNAs have been generated from human tumors and the corresponding normal tissues from the same donor. BioChain offers Primary Pair (PP), as well as Primary and Metastatic Pair (PM) products. Primary Pair Total RNAs are those that have been isolated from primary tumors and its adjacent unaffected normal tissue. Primary Metastatic Pair Total RNAs have been isolated from primary tumors and corresponding metastatic tumors. Total RNA is isolated by modified guanidine thiocyanate techniques and stored in RNA storage buffer. This product is a useful tool for accelerating gene expression analysis by identifying tumor-specific genes and tumor metastatic genes.

Quality Control

  • The integrity of the RNA is examined by visual inspection for the presence of intact bands of 18s and 28s ribosomal RNA when electrophoreses on a denaturing agarose gel
  • The quality and purity of total RNA were tested by spectrophotometer. A260/280 is between 1.8 and 2.1(detected in 10 mM Tris-HCl, pH 7.5).
