|---|
PNA(Peptide nucleic acid)為具有類多肽骨架的DNA類似物，可以經由人工合成製造，PNA 具有一種結構N-(2-aminoethyl) glycine。使對於標的的DNA或RNA結合親和力和穩定性大大提高。儘管骨架的結構變化，但 PNA 可用於 DNA 的各種應用，因為它可以像 DNA 一樣與標的序列互補結合。特點：
| PNA | DNA | |
| Binding Affinity | At Least 1°C Higher Tm per Base | - |
| Hybridization rate | 100-5000 Times Faster | - |
| Salt concentration in hybridization | Independent | Dependent |
| ΔTm for single nucleotide mismatch | <10°C | <15°C |
| ChemicalStability | Stable | Unstable in Acidic or Basic condition |
| BiologicalStability | Enzyme-Resistant | Degradable by Nuclease |

一、Panagene Custom PNA
客製化PNA序列，可以依照不同的需要合成下列兩種方案：
1. fluorescent dye-labeled PNA可label螢光
2. unlabeled PNA
序列設計，除了一般的DNA序列之外，亦可以加入Linker ( C3-NH2, C4-NH2, C6-NH2, C12-NH2, Polyethylene Glycol linker, E linker )，Base modification (D (2,6-diaminopurine), J (Pseudoisocytosine), I (Inosine) )等相關的modification。
