This digoxigenin-labeled poly (dT) oligonucleotide probe recognizes poly (A) tails of mRNAs within tissue sections. Specific hybridization of this probe to poly (A) tails in FFPE tissues indicates that the test material contains intact mRNA. This probe can be used as a control when running specific RNA targeting probes. Weak or light staining in a test sample indicates that specifically targeted mRNA may be compromised.
Approximately 20 tests at 20 microliters per test
