| Product Name | Fast Cell Direct Probe RT-qPCR Kit |
| Catalog No. | RESK-0064 |
| Description | This kit enables direct quantitative gene expression analysis from a wide range of cultured animal cells-including adherent and suspension cell lines, primary cultured cells, various stem cells, and iPS cells-without RNA extraction. The streamlined workflow from template preparation through reverse transcription to gene expression analysis can be completed in as little as 1.5 hours, with short hands-on time, simple operation, and a low error rate. The kit includes cell lysis reagents, washing reagents, gDNA removal reagents, reverse transcription reagents, and a probe-based qPCR detection mix for effortless gene expression analysis. |
| Intended Use | For direct two-step probe-based RT-qPCR quantitative gene expression analysis from cultured animal cells without RNA purification (cell lysis + reverse transcription + probe-based qPCR). |
| Principle / Technology | Cultured cells are lysed directly with the FCD Lysis Buffer, washed, and the reaction stopped; genomic DNA is removed with DNase I. The lysate is reverse transcribed with the 4x RT mix, and cDNA is quantified by probe-based qPCR using an antibody-based hot-start master mix. |
| Detection Method | TaqMan probe-based real-time fluorescence detection. |
| Sample Type | Various cultured animal cells, including adherent and suspension cell lines, primary cultured cells, various stem cells, and iPS cells; validated with inputs of 10^3 to 10^6 cells. |
| Performance Range / Specifications | Complete workflow (cell lysis, reverse transcription, and qPCR) in as little as 1.5 hours Amplicon length: 80-300 bp Annealing temperature: 60°C Template GC content: 30%-70% Reverse transcription system tolerates up to 55% cell lysate qPCR system tolerates up to 46% cDNA input Fully premixed qPCR reactions stable for 48 hours; kit stable for 7 days at 4°C |
| Sensitivity / LOD | In tests with 293 cells in different growth states at inputs of 10^3, 10^4, 10^5, and 10^6 cells, this kit delivered lower Ct values, better reproducibility, and higher sensitivity than competitor products. |
| Specificity | Antibody-based hot start ensures amplification specificity; probe-based detection provides additional target specificity. |
| Reaction Conditions / Protocol | Two-step workflow: 1. Cell lysis with FCD Lysis Buffer, washing with FCD Washing Buffer, reaction stop with FCD Stop Solution, and gDNA removal with DNase I 2. Reverse transcription with 4x FCD RT Mix 3. Probe-based qPCR with 2x FCD Probe qPCR Mix (recommended annealing temperature: 60°C) |
| Components / Formulation | FCD Lysis Buffer (2 mL / 5 mL) FCD Washing Buffer (8 mL / 20 mL) FCD Stop Solution (100 μL / 250 μL) DNase I (80 μL / 200 μL) 4x FCD RT Mix (200 μL / 500 μL) 2x FCD Probe qPCR Mix (2 mL / 5 mL) RNase-Free Water (2 mL / 5 mL) (Volumes shown for the 40 rxns / 100 rxns packages, respectively) |
| Storage Conditions | Store unopened FCD Lysis Buffer and FCD Washing Buffer at -25 to -15°C; once thawed, keep at 4°C and avoid contamination. Store all other components long-term at -25 to -15°C. |
| Shelf Life | 1 year. |
| Package Specifications | 40 rxns; 100 rxns |
| Product Form | Mix |
| Concentration | 4x (RT mix); 2x (qPCR mix) |
| Expiration Date / Stability | Valid for 1 year. The kit is stable for 7 days at 4°C, and fully premixed qPCR reactions (with cDNA, primers/probes, and water) remain stable for 48 hours at various temperatures, accommodating instrument queue waiting. |
| Compatibility | Compatible with the vast majority of real-time fluorescence quantitative PCR instruments. |
