用于人潜伏转化生长因子- β 1的检测和测定
人潜伏转化生长因子-β1 (TGF-β1)试剂盒用于血浆、细胞培养上清等生物体液中潜伏TGF-β1的定量检测和测定。TGF-β1主要由血小板和骨骼产生,大多数有核细胞和肿瘤也产生少量TGF-β1。TGF-β1刺激间充质来源的细胞,但抑制上皮或神经外胚层来源的细胞。TGF-β1与潜伏期相关蛋白(Latency Associated Protein, LAP)结合形成潜伏复合物。该试剂盒检测该复合物的LAP实体。
该检测基于夹心ELISA方法,将样品添加到酶联免疫吸附试验(ELISA)带材板上,该带材板上预先涂有捕获的细胞因子特异性抗体。捕获的细胞因子通过添加生物素化的检测抗体来检测,然后添加链霉亲和素-辣根过氧化物酶,该酶与生物素化的抗体结合。添加显色酶底物3,3 ‘,5,5 ’四甲基联苯胺(TMB)可得到着色产物,其强度与样品中细胞因子的浓度成正比。细胞因子的浓度是通过与平行分析的细胞因子标准品的连续稀释进行比较来确定的。

Representative Standard Curve
• Reportable range: 0.32 - 32 pM. This is the concentration range in which measurement of the analyte can be done with the highest precision, accuracy, and linearity. Recombinant human LAP (latency associated protein) homodimer is the analyte standard of this ELISA. Determination of latent TGF-β1 using the standard curve is based on a molar comparison. 1 pM LAP (54 pg/mL) corresponds to 1 pM latent TGF-β1 (80 pg/mL).
• Sensitivity: The limit of detection of this assay is 0.13 pM. This is the analyte concentration with absorbance two standard deviations higher than the zero standard.
• Recovery: A mid-curve recovery of 100% was determined by dilution of plasma samples in repeated experiments.
• Precision: The intra-assay precision of this assay is 3.0% (CV). The inter-assay precision of this assay is 10.4% (CV).
