For PCR assay, specimens were processed by lysis method as described previously [ 22].
Assaying specimens from other reservoirs (e.g., genital secretions, urine, plasma) may have demonstrated a difference between the two groups.
For all assays, specimens were obtained from female patients under fifty years of age, from the flank and thigh subcutaneous regions only.
MKP-1 was expressed in histologically normal colon epithelial cells and the pattern and intensity of staining were similar in all assayed specimens.
To determine the specificity of the two RT-PCR assays, specimens from both 35 bone marrow and 35 peripheral blood normal donors were evaluated.
The RPM-Flu assay of specimen USDA_13 was reported negative for detection of avian influenza virus, but the same assay also reported the specimen to be positive for avian metapneumovirus.
Samples are thawed at a central laboratory for assay or specimen quality control and sample quality data is uploaded directly to the database by the central laboratory.
There were no significant differences between duplicates when examined by assay and specimen type.
To review participants for inclusion in an ancillary study, investigators need to align, integrate and evaluate a range of data types, including consent, clinical, assay, and specimen.
Whether one uses a qPCR assay for specimen selection or uses parallel microarray readout for final approval, the developed 13-gene TCP profile will provide an additional tool for objective assessment of sufficient tumour cell content in breast cancer tissue.
