Changyu Bio quotes RayBiotech NAE-PBNA-MAG (cell-free nucleic acid extraction from plasma) and NAE-BIS-MAG (DNA bisulfite conversion), two magnetic-bead kits often ordered together for cfDNA methylation research. We serve research laboratories in South Asia, the Middle East, Africa, Southeast Asia, Europe and the Americas. No price is published. Research Use Only.
Typical workflow
Plasma → cfDNA extraction (NAE-PBNA-MAG) → bisulfite conversion (NAE-BIS-MAG) → methylation-specific qPCR. Unmethylated cytosines are converted to uracil while 5-methylcytosine stays unchanged, so primers or probes can tell them apart.

Common questions
- What is NAE-PBNA-MAG? RayBiotech Peripheral Blood Cell-free Nucleic Acid Extraction Kit (Magnetic Bead Method), 50 samples, for human plasma.
- What is NAE-BIS-MAG? RayBiotech DNA Bisulfite Conversion Kit (Magnetic Bead Method), 50 samples, converting unmethylated cytosine to uracil for methylation analysis.
- Can the two kits be used together? Yes. cfDNA extracted with NAE-PBNA-MAG can be bisulfite-converted with NAE-BIS-MAG before methylation qPCR.
- How should the kits be stored? RayBiotech lists dry storage at 2–30 °C for up to 24 months.
- Can you ship to Bangladesh? Yes. Send the quantity and destination city; availability and lead time are confirmed on the quotation.
