General description

Human placental DNA is isolated from a single female donor placenta, but will contain some maternal DNA. The sex has been determined using hybridization with DNA probes.

Application

Deoxyribonucleic acid from human placenta has been used:
  • to compare the efficiency of DNA quantification methods
  • as a standard in real-time PCR analysis of DNA samples from bladder cancer cell lines
  • as an internal control to estimate the degree of fragmentation of circulating DNA
  • for restriction digest analysis to identify low copy repeat regions of human chromosome 22q11
  • to compare the 70-bp P5 exon sequence between DNA of different human and primate species
  • to calculate copy number of genes, relative to normal human tissue
  • in PCR reactions
For use in Southern hybridizations.

Recommended products

Solutions of DNA have been stored successfully for several months at 4 C, in 10 mM Tris, pH 7.5 - 8.0, with 1 mM EDTA and without a bacteriostatic agent. At low concentrations, about 25 μg/ml, DNA tends to absorb onto the surfaces of plastic tubes.

Although circulating DNA (ctDNA) could be an attractive tool for early cancer detection, diagnosis, prognosis, monitoring or prediction of response to therapies, knowledge on its origin, form and rate of release is poor and often contradictory. Here, we describe an

Many tumors have large homozygous deletions of the CDKN2A locus (encoding p14(ARF) and p16) and of CDKN2B (p15). Our aim was to determine which gene is the major target in bladder cancer. We used quantitative real-time PCR (RTQ-PCR) to determine

Tumor types can be defined cytologically by their regions of chromosomal amplification, which often results in the high expression of both mRNA and proteins of certain genes contained within the amplicon. An important strategy for defining therapeutically relevant targets in

The imprinted gene PLAGL1 is an important regulator of apoptosis and cell cycle arrest. Loss of its expression has been implicated in tumorigenesis in a range of different cancers, and overexpression during fetal development causes transient neonatal diabetes mellitus (TNDM).

The human CYP19 gene encodes aromatase, which converts androgens to estrogens. CYP19 mRNA variants are transcribed mainly from three promoters. Quantitative RT-PCR was used to measure the relative amounts of each of the three transcripts and determine the on/off state
