Probetex●PTX-002S ●Sheep Anti-Rat Fx1A Serum【選購指南】

??【產品基礎信息】  

- 貨號:PTX-002S  

- 英文名:Sheep Anti-Rat Fx1A Serum

- 中文名:綿羊抗大鼠Fx1A血清  

- 品牌:Probetex  

- 規格:25 ml/瓶  

- 保存條件:-20℃避光保存,避免反復凍融  

- 應用領域:免疫介導的膜性腎小球腎炎(Heymann Nephritis)模型構建、腎病研究、藥物篩選等  

- 核心成分:高特異性抗大鼠Fx1A抗體,經嚴格篩選和質控,確保實驗可重復性  


??【詳細介紹】  

1?? 產品背景與研發理念  

Probetex公司自1997年起專注于腎病模型研究,其核心產品線包括抗GBM、抗Fx1A和抗Thy-1血清,致力于為科研和制藥行業提供高標準的動物模型構建工具。PTX-002S基于綿羊抗大鼠Fx1A抗體,通過誘導亞上皮免疫復合物沉積,模擬人類膜性腎病的病理特征,如足細胞損傷、蛋白尿和腎小球硬化。  

2?? 作用機制與病理表現  

- 免疫復合物沉積:Fx1A抗原存在于大鼠腎小球足細胞表面,抗體結合后形成上皮下免疫復合物,激活補體系統,引發炎癥反應。  

- 病理進程:注射后3-5天出現蛋白尿,8-10天腎小球IgG線性沉積,3周后形成新月體及廣泛纖維化。  

- 模型特點:高度可重復性,適用于評估抗炎藥物、靶向療法及基因干預效果。  

3?? 實驗操作指南  

- 劑量推薦:每瓶血清可誘導至少25只大鼠(175-200g)模型,推薦尾靜脈注射劑量為0.4-0.5ml/100g體重。  

- 關鍵步驟:  

1. 麻醉大鼠后快速注射血清,確保劑量進入體內;  

2. 注射后連續監測蛋白尿水平(24小時尿蛋白定量);  

3. 3周后處死取材,進行組織病理學分析(HE染色、免疫熒光等)。  


??【核心優勢】

1?? 高特異性與穩定性  

- 抗體純度>95%,經熱處理(56℃ 30分鐘)滅活補體,降低非特異性反應風險。  

- 批次間差異小,支持長期實驗規劃。  

2?? 廣泛的應用場景  

- 基礎研究:揭示膜性腎病的分子機制(如補體激活、足細胞凋亡);  

- 藥物開發:評估新型免疫抑制劑、納米載體藥物的療效;  

- 教學示范:作為醫學院校病理學實驗的經典模型。  

3?? 專業的技術支持  

- Probetex提供配套的BioScout™免疫熒光參考抗體(如BS-001GBM),精準定位抗原分布;  

- 定制化服務:支持劑量優化、病理切片分析及數據解讀。  


?【常見問題與解答】  

Q1:PTX-002S能否用于小鼠模型?  

A:驗證僅限大鼠,需自行預實驗確定最佳劑量。  

Q2:每瓶血清的實際效價如何?  

A:每瓶含足夠抗體誘導25只大鼠模型,效價穩定,支持分裝保存。  

Q3:注射后如何判斷模型成功?  

A:成功標志為蛋白尿(>200mg/24h)、腎小球IgG線性沉積及系膜細胞增生。  

Q4:能否與其他抗體聯用?  

A:建議單獨使用,若需聯用需驗證兼容性(如補體激活干擾)。  

Q5:運輸過程中如何避免降解?  

A:全程干冰運輸,收到后立即轉移至-20℃,避免反復凍融。
