Human Telomeric Repeat–Containing RNA Detection qPCR Kit (TERRA, Cat. No. 9028)

Quantifies total and chromosome-specific TERRA transcripts by RT-qPCR using a proprietary DNA linker strategy for highly specific detection.

• Best for: measuring TERRA expression in telomere biology, aging, cancer, and oxidative stress studies
• Measures: total TERRA and chromosome-specific TERRA
• Proprietary DNA linker strategy minimizes genomic DNA interference without harsh DNase treatment, improving assay specificity and preserving TERRA integrity
• Validated primer sets confirmed by qPCR with no amplification from genomic DNA or no-RT controls

Recommended for: telomere biology, aging research, cancer biology, oxidative stress, and genomic stability studies

Human TERT DNA Copy Number Quantification qPCR Assay Kit (TERT, Catalog No. 9018)

Quantifies human TERT (hTERT) DNA copy number by qPCR using a single-copy reference for accurate assessment of telomerase gene amplification in genomic DNA.

• Best for: measuring hTERT copy number in cancer, cell immortalization, and telomere biology research
• Measures: hTERT DNA copy number relative to a single-copy reference (SCR) gene using the comparative ΔΔCq method
• Includes a reference DNA sample with a defined 1:1 hTERT-to-SCR ratio for reliable copy number calculation across samples
• Primer sets are validated by qPCR melt curve analysis, gel electrophoresis, and amplification efficiency testing to ensure assay specificity and performance

Recommended for: cancer biology, telomere research, genomic stability studies, and validation of hTERT-immortalized cell lines
