PLK1
PLK1（Polo樣激酶1）是調控細胞分裂的關鍵蛋白，屬于絲氨酸/蘇氨酸激酶家族。該蛋白通過磷酸化下游靶點驅動有絲分裂進程，確保染色體精準分離和胞質分裂完成。研究發現，PLK1在多種惡性腫瘤中異常高表達，其活性失控會導致基因組不穩定性，促進腫瘤增殖與轉移，尤其在乳腺癌、肺癌和結直腸癌中與預后不良相關。針對這一靶點，全球已開發出BI 2536、Volasertib等小分子抑制劑，其中Volasertib聯合化療在急性髓系白血病II期試驗中顯示出生存期延長，但因心臟毒性未獲FDA批準。近年來研究者嘗試通過聯合用藥策略降低毒副作用，同時探索PLK1與PARP抑制劑在DNA損傷修復中的協同效應，為實體瘤治療開辟新方向。我國正大天晴等企業也在推進同類藥物的臨床試驗。

驗證數據
Immunohistochemistry of paraffin-embedded human colon cancer using CSB-PA018193LA01HU at dilution of 1:100
Immunofluorescence staining of A549 cells with CSB-PA018193LA01HU at 1:133, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
