cDNA Panel

Introduction to cDNA Panel

BioChain's cDNA panel is comprised of 5 tubes each containing 10 µl of PCR Ready First Strand cDNAs from 5 tissues. This is the economical way to get cDNA from multiple tissues. These cDNAs are ideal for analyzing gene expression patterns and discovering novel genes. All cDNAs in a panel are made under optimal and consistent conditions, which ensure that the genetic representation is maintained from total RNA to cDNA.

Features

  • Ready to use for PCR quantification of gene expression
  • Oligo dT primer used to ensure the entire 3' end of cDNA is present
  • With some cDNA used as templates, 12 kb PCR amplicon was obtained to ensure intact cDNAs
  • The largest selection of cDNAs from different tissues on the market
  • Placenta cDNA is included in every panel as an interpanel control
  • Documentation of tissues' clinical histories available
  • Applications

  • PCR amplification of known genes for expression
  • Quantification of low copy gene expression in multiple tissues
  • Identification of tissue-specific expression of target genes
  • Analysis of gene expression in rare tissues
  • Verification of genetic mutation
  • Comparison of a specific gene between different tissues
  • Analysis of mRNA alternative splicing
  • Quality Control

  • The integrity of the RNA used for cDNA synthesis 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 2.0 (detected in 10 mM Tris-Cl, pH 7.5). The ratio of 28S/18S is ≥1.
  • The RNA used for cDNA synthesis is treated by DNase I, and is tested as DNA free RNA by PCR.
  • The synthesized human, animal, and cell line cDNA was selected to ensure its full length. The cDNA was used as template for PCR amplification of ß-actin gene and an 838 bp ß-actin band was visualized on 1% agarose gel. ß-actin control primer is included. It is enough for 10 PCR reactions.
  • The synthesized plant cDNA was used as template for PCR amplification of chloroplast gene. A 458 bp chloroplast band was visualized on 1% agarose gel. Chloroplast control primer is included. It is enough for 10 PCR reactions.
