PSAP
PSAP,全稱為前鞘脂激活蛋白原,常被簡稱為prosaposin,也有SAP前體這樣的別名。它是體內脂質代謝的重要調節因子前體,可分解為四個功能片段,幫助細胞內溶酶體處理鞘脂類物質的降解與循環,維持細胞正常的脂質平衡狀態。除此之外,這種蛋白在神經系統中含量較高,具有明顯的神經保護作用,能支持神經細胞的存活與分化,減少有害物質對神經細胞的損傷。
若PSAP相關功能出現異常,可能導致鞘脂類物質在體內堆積,引發代謝性疾病,這類疾病對神經系統影響尤其顯著,患者可能出現認知減退、運動障礙等癥狀。目前針對PSAP的研究多聚焦于神經保護領域,部分團隊嘗試用其活性片段開發治療神經退行性疾病的候選藥物,比如緩解阿爾茨海默病的神經損傷,但相關研究仍處于早期階段,尚未有成熟藥物應用于臨床。

IHC image of CSB-PA018836DA01HU diluted at 1:500 and staining in paraffin-embedded human lung tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.
Immunofluorescence staining of MCF-7 cells with CSB-PA018836DA01HU at 1:166, 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).
