Actin is a highly conserved protein and an essential component of cell cytoskeleton and plays an important role in cytoplasmic
streaming, cell shape determination, cell division, organelle movement and extension growth. Preferentially expressed in young
and expanding tissues, floral organ primordia, developing seeds and emerging inflorescence. Antibodies against plant Actin are
useful as loading controls for Western Blotting.

答：可能的原因有：
1、目的蛋白有多個(gè)修飾位點(diǎn)，本身可以呈現(xiàn)多條帶，建議查閱文獻(xiàn)或進(jìn)行生物信息學(xué)分析，獲得蛋白序列的修飾位點(diǎn)信息，通過(guò)去修飾確定蛋白實(shí)際大小；
2、樣本處理過(guò)程中目的蛋白發(fā)生降解,建議加入蛋白酶抑制劑；樣本處理時(shí)在冰上操作；
3、雜蛋白多，建議處理目的蛋白；
4、抗體特異性不強(qiáng)，建議使用特異性強(qiáng)的抗體；
5、抗體孵育時(shí)間過(guò)久，建議減少抗體孵育時(shí)間；
6、二抗與抗原有交叉反應(yīng)，建議選擇合適的封閉物；
7、二聚體或多聚體存在，建議增加蛋白質(zhì)變性過(guò)程及強(qiáng)度；
8、底物顯色與曝光時(shí)間過(guò)長(zhǎng)，建議縮短顯色及曝光的時(shí)間。
