【BlockPRO™無蛋白封閉緩衝液】Protein free blocking buffer Visual Protein BF01-1L
【blocking封閉緩衝液】非蛋白質配方-有效增加訊號及最小化背景值
轉印膜 (transfer membrane)和抗體反應之前,須進行封閉(blocking),以封閉 (blocking) 轉印膜上蛋白質外空白區域,減少抗體 (蛋白質) 吸附,造成之背景值增加。傳統方法常用0.05%-0.5%的BSA、10% 的小牛血清、1%明膠(gelatin)、3-5% non-fat milk (配在 TBST 或 PBST 裡),進行封閉(blocking)。若blocking中的蛋白質被目標抗體辨認,則造成背景值增加。Visual protein 提供的 BlockPRO Protein-Free Blocking Buffer封閉緩衝液是一種非蛋白質配方,可以有效地增加訊號,最小化背景值;應用廣泛,適用於 Western blotting 與 ELISA 等免疫學實驗。
BlockPRO™ Protein-Free Blocking Buffer | 貨號BF01-1L
產品介紹: BlockPRO™不含蛋白質的封閉緩衝液是一種非蛋白質配方,能有效降低遮蓋液與蛋白樣本的交互作用,避免物種干擾。可提高靈敏度並最小化背景噪音,在免疫測定中比傳統的基於蛋白質的封閉緩衝液呈現更好的結果。 BlockPRO™無蛋白封閉緩衝液的合成配方使其適用於PVDF和硝酸纖維素平台,抗生物素蛋白/生物素系統,磷蛋白檢測以及其他免疫化學應用。應用廣泛,適用於 Western blotting 與 ELISA 等免疫學實驗。
產品特點:
- 高性能:比傳統的阻塞緩衝器提供更好的特定信號和更少的背景噪聲
- 多種應用:適用於蛋白質印跡,斑點印跡,ELISA和其他免疫測定
- 高質量控制:確保批次間的一致性,以確保長期獲得最可重複的結果


Figure 1. BlockPRO™ Protein-Free Blocking Buffer is better than protein-based blocking buffers (skim milk, BSA and casein) for detection of target protein in Western blotting. THP-1 cell lysates were prepared and separated by electrophoresis. The proteins were transferred to PVDF and blocked for 1 hour at room temperature with the indicated blocking buffer, probed with mouse anti-pAMPK followed by anti-mouse HRP and detected by chemiluminescence. All results were exposed to X-ray film for 30 seconds.


Figure 2. BlockPRO™ Protein-Free is suitable for various protein antigen detection, such as high molecular weight protein, tACC; phosphoprotein, pAMPK; abundant protein, GAPDH; low molecular weight protein, histone H3. THP-1 cell lysates were prepared and separated by electrophoresis. The proteins were transferred to PVDF and blocked for 1 hour at room temperature with BlockPRO™ Protein-Free Blocking Buffer. Antibodies designed to probe the indicated proteins were used. All the signals were detected by chemiluminescence and were exposed to X-ray film.


Figure 3. BlockPRO™ Protein-Free Blocking Buffer can be used in both PVDF and nitrocellulose platform. Hela cell lysates were prepared and separated by SDS-PAGE. The proteins were transferred to PVDF or nitrocellulose membranes. The membranes were blocked for overnight at 4 °C with BlockPRO™ Protein-Free Blocking Buffer or 5% skim milk, probed with mouse anti-histone H3 followed by anti-mouse HRP and detected by chemiluminescence. All results were exposed to X-ray film for 30 seconds.
