| Background | Autophagy is a catabolic process for the autophagosomic-lysosomal degradation of bulk cytoplasmic contents. Autophagy is generally activated by conditions of nutrient deprivation, but it has also been associated with a number of physiological processes including development, differentiation, neurodegenerative diseases, infection, and cancer. Autophagy marker Light Chain 3 (LC3) was originally identified as a subunit of microtubule-associated proteins 1A and 1B (termed MAP1LC3) and subsequently found to contain similarity to the yeast protein Apg8/Aut7/Cvt5 critical for autophagy. Three human LC3 isoforms (LC3A, LC3B, and LC3C) undergo post-translational modifications during autophagy. Cleavage of LC3 at the carboxy terminus immediately following synthesis yields the cytosolic LC3-I form. During autophagy, LC3-I is converted to LC3-II through lipidation by a ubiquitin-like system involving Atg7 and Atg3 that allows for LC3 to become associated with autophagic vesicles. The presence of LC3 in autophagosomes and the conversion of LC3 to the lower migrating form, LC3-II, have been used as indicators of autophagy. |

保存條件：
LC3B Rabbit Polyclonal Antibody (KO Validated) -20ºC保存，Western一抗稀釋液-20ºC或4ºC保存，一年有效。Western一抗稀釋液優先推薦4ºC保存，長期不使用可以考慮-20ºC保存，但凍融可能會導致出現輕微的渾濁和少量不溶物。
注意事項：
如果本抗體用于Western blot (WB)、免疫熒光(IF)、免疫細胞化學(ICC)等實驗，請注意回收使用過的稀釋抗體。回收的抗體通常至少可以重復使用5-10次。稀釋后的抗體，包括已經使用過的稀釋抗體，請4℃保存。
回收后重復使用的抗體，使用方法同新鮮稀釋的抗體。如果在重復使用過程中發現抗體出現輕微混濁現象，可以10,000g離心1-3分鐘，取上清用于后續檢測。如果回收的抗體出現明顯的絮狀物或長霉長菌等情況，則可以考慮廢棄該抗體。
提供的Western一抗稀釋液也可以用于免疫熒光(IF)、免疫組化(IHC)、免疫細胞化學(ICC)等適當用途。如果希望獲得最佳的檢測效果，請考慮使用上述檢測專用的一抗稀釋液。
本產品僅限于專業人員的科學研究用，不得用于臨床診斷或治療，不得用于食品或藥品，不得存放于普通住宅內。
為了您的安全和健康，請穿實驗服并戴一次性手套操作。
使用說明：
請根據抗體的實際用途選擇相應的使用方法。
1. Western檢測：
a. 按照推薦的稀釋比例用Western一抗稀釋液稀釋抗體。
b. 把經過封閉的蛋白膜與稀釋好的一抗4℃緩慢搖動過夜或室溫緩慢搖動2小時，確保稀釋的抗體至少能在搖動的瞬間覆蓋蛋白膜。
c. 回收稀釋的一抗，4℃保存以備下次繼續使用。
d. 按照Western的實驗步驟進行后續的洗滌、二抗孵育、洗滌和檢測等操作。
2. 免疫染色：
可以使用免疫染色一抗稀釋液(P0103)稀釋抗體，使用后注意回收稀釋好的一抗，
3. 其它實驗操作請自行參考適當的protocol進行。
