- Phenolic / complex plant RNA (CYRN53)
How to pick an extraction kit
- Shipping — CYDN, CYDR and CYRN kits ship ambient (no ice packs). Storage after arrival still follows the spec table: Proteinase K in CYDN07 at −20°C; Buffer RL in CYRN03 at 4°C; CYRN53 at 15–25°C and must not be refrigerated.
- DNA vs RNA, animal vs plant — CYDN07 for cell/tissue genomic DNA; CYDN14 for plant DNA. CYRN28 for cell/tissue RNA; CYRN53 for phenolic plant RNA; CYRN03 when you want TRIzol lysis plus a column.
- gDNA carry-over — CYRN28 and CYRN53 include a genomic-DNA elimination column, so a separate DNase step is usually unnecessary.
- Cleanup after electrophoresis or PCR — CYDR01 for gel slices; CYDR02 for PCR products.
Frequently asked questions
- Do extraction kits need ice packs? No. This family ships ambient. Keep Proteinase K (CYDN07) at −20°C after arrival; do not refrigerate CYRN53.
- Plant RNA or plant DNA? CYRN53 for complex/phenolic plant RNA (store 15–25°C). CYDN14 for plant DNA (CTAB-style; warm buffers at 55°C if they precipitate).
- CYRN03 vs CYRN28? CYRN03 is TRIzol (Buffer RL at 4°C) plus a silica column. CYRN28 is phenol-free Plus chemistry with a gDNA-elimination column for cells and tissues.
- How many preps? Common listed formats: CYDN07 50/100; CYDN14 50/100/200; CYDR01 50/100; CYRN03/27/28/53 typically 50 preps. Quote the catalog you need.
- Is the viral RNA kit for diagnosis? No. CYRN27 is for research amplification from plasma, serum or other cell-free fluids. Research Use Only.

TriPure / TRIzol alternative
Looking for a TriPure or TRIzol isolation reagent? Changyu RNApure Total RNA Kit (CYRN03) is a spin-column alternative to phenol-chloroform reagents such as TriPure and TRIzol: it avoids phase separation and organic solvent handling while purifying high-quality total RNA from cells and tissues. Research use only (RUO) — see CYRN03 or request a quote.
SDS & Documentation FAQ
Do you provide SDS (Safety Data Sheets) for your RNA isolation reagents?
Yes. SDS/MSDS documents for our RNA and DNA extraction reagents are available on request – contact us through the Request a Quote page and we will send the matching document for your catalog number.
Where can I find reagent composition information?
Composition details are documented in each product manual. For purity questions after extraction, read our guide: Why an RNA A260/A280 of 1.8 Is Not a Purity Pass.
Looking for TriPure / TRIzol-style RNA isolation reagent? See our CYRN03 RNApure option.
