| Product Description | 无形体抗原（ANAG1107）是通过原核系统表达得到的重组抗原，该蛋白可用于检测抗原抗体的免疫反应。 |
| Molecular Name | ANA |
| Product Introduction | ANA：抗核抗体，是一类能与细胞核自身成分结合的自身抗体，是多种自身免疫病的血清学标志。 |
| Species | 无形体 |
| Host | E.coli |
| Purity | > 85% as determined by Tris-Bis PAGE |
| Purification | Affinity purification chromatography |
| Storage Condition | The lyophilized protein can be stored at -20 °C.After re-solubilization, the protein can be stored at -20°C to 40°C for one month without detectable loss of activity. The protein product is stable for 12 months from the date of receipt when stored at -80°C. |
| Formulation | PBS with 0.05% proclin300,50% glycerol,pH7.3. |
| Shipping Condition | In general, liquid samples are shipped on dry ice and lyophilised samples are shipped on blue ice. |
| Background | In immunology, an antigen (Ag) is a molecule or molecular structure that can bind to a specific antibody or T-cell receptor. The presence of antigens in the body may trigger an immune response. |
| Application | For the development of immunological kits such as colloidal gold, elisa, or for serological research |
| Product Declaration | 该产品仅供科研使用，不可直接用于人体或注射。 |

重组蛋白抗原和天然抗原相比有什么优点？
重组抗原是通过基因工程在体外表达的抗原，其主要优点包括：（1）安全性高： 无需培养活病毒，避免了病毒泄漏和灭活不彻底的风险。（2）纯度高、质量稳定： 生产过程可控，能获得高纯度、无杂蛋白干扰的抗原，批间一致性更好。（3）可定向设计： 可以只表达具有关键免疫原性的片段（如VP1是口蹄疫病毒的主要免疫原性蛋白），提高检测的特异性和灵敏度。
