PBS, pH 7.4, 15mg/ml Bovine Serum Albumin as Stablizer and 50% Glycerol. Store at -20°C.
Do not aliquot the antibody.
1:100-1:1,000 for immunohisto/cytochemistry
1:1,000-1:100,00 for ELLSA and Western blotting with chromogenic substrates
1:1,000-1:10,000 for Western blotting with ECL substates Optimal dilutions should be determined by the end user.
The antibody was purified from antisera by immunoaffinity chromatography using antigens coupled to agarose beads.
Antibody Specificity:Based on immunoelectrophoresis and/or EL1SA,the antibody reacts with whole molecule pig IgG.
lt also reacts with the light chains of other pig immunoglobulins. No antibody was detected against non-immunoglobulin
serum proteins.The antibody may cross-react with immunoglobulins from other species.
Store at -20°C. Avoid repeated freeze / thaw cycles.The expiration date may be extended if test results are acceptable for
the intended use.
For in vitro research use only,not for diagnostic or therapeutic use.This product is not a medical device.

答:可能的原因有:
1、膜沒有完全均勻濕透,建議 使用100% methanol浸透膜;
2、洗膜不充分,可以增加洗液體積和洗滌次數;
3、電極不平衡或者加樣位置偏斜,可以調整電極和加樣;
4、封閉物用量不足,可以提高封閉物濃度,孵育時保證封閉液完全浸沒轉印膜;
5、封閉物使用不當,比如檢測生物素標記的蛋白時不可用脫脂奶粉封閉;
6、封閉時間不夠,一般情況下室溫37度封閉1小時以上或者4度封閉過夜;
7、抗體非特異性結合,可以降低抗體濃度,減少孵育時間;
8、一抗稀釋度不適宜,可以對抗體進行滴度測試,選擇適宜的抗體稀釋度;
9、一抗孵育的溫度偏高,建議4℃結合過夜;
10、抗體濃度過高或洗滌不夠,建議降低抗體濃度,增加洗滌次數和時間;
11、化學顯色底物過多,建議按說明書加入適量的顯色底物。
答:可能的原因有:
1、膠濃度不對,不同濃度的膠跑出的蛋白條帶的位置可能有所偏差,可以調整濃度;
2、抗體孵育不充分,建議增加抗體濃度,延長孵育時間;
3、酶失活,建議直接將酶和底物進行混合,如果不顯色則說明酶失活了。選擇在有效期內、有活性的酶聯物;
4、目的蛋白存在翻譯后修飾或剪切體,建議查詢相關文獻確定;
5、標本中不含靶蛋白或靶蛋白含量太低,建議設置陽性對照比對結果,增加標本上樣量。
