◆基本信息
L-012 是一種高靈敏度的化學(xué)發(fā)光(CHL)探針,比魯米諾(Luminol)試劑更有效。L-012 與多種類型的活性氧反應(yīng),這些活性氧來自人血液和口腔中激活的中性粒細(xì)胞或者大鼠腹膜腔。該產(chǎn)品可以用于有辣根過氧化物酶的ELISA 試劑盒,可提高反應(yīng)靈敏度。
結(jié)構(gòu)式
溶解及保存:蒸餾水溶解成20 mM/L(6.23 mg/mL)的水溶液,再用50 mM/L的Tris鹽酸緩沖液(pH 7.5)稀釋 至最終濃度為500 μM/L(有細(xì)胞的反應(yīng)體系)。另外,在沒細(xì)胞參與的反應(yīng)體系中時,建議使用終濃度為5~50 μM/L。母液冷凍保存,使用時再稀釋。

Q&A
Q: L-012能滲入細(xì)胞嗎?
A: 由于L-012對脂質(zhì)高度親和,它比luminol和lucigenin更能具有細(xì)胞滲透性。另一方面,ROS無限制地在胞外釋放。因此L-012被認(rèn)為也能
檢測胞外ROS。
Q: L-012的使用濃度如何?
A: 這取決于應(yīng)用和條件。
[體外] 培養(yǎng)細(xì)胞(EoL-1細(xì)胞): 500 ~ 800 μmol/L.
全血和分離的中性粒細(xì)胞: 400 μmol/L
多形核中性粒細(xì)胞(PMNs)(由小鼠中分離): 2 mmol/L
無細(xì)胞的樣品: 4 μmol/L, 15 μmol/L, and 50 μmol/L
[體內(nèi)] Balb/c 小鼠[皮下]: 20 ~ 80 μL of L-012(5mg/mL)
Balb/c 小鼠[腹膜內(nèi)]: 100 μL of L-012 (15mg/mL)
C57BL/10.Q (B10.Q) 小鼠 [腹膜內(nèi)]: 1 ~ 75 mg/kg
Q: 是否可用于動物活體成像?
A: 如果所用的小動物成像儀中有發(fā)光檢測探頭,就可以進(jìn)行檢測。以下是文獻(xiàn)報道過的儀器型號:
?IVIS 100 imaging systems
?Infinite M200 [Tecan]
?Luminescence Reader BLR-201 [Aloka]
?Beckman-Coulter DTX880 multimode plate reader [Beckman]
Q: 是否可用于固定細(xì)胞?
A: 目前尚無證據(jù)表明,活性氧(ROS)在細(xì)胞活性停止后仍然存在。普遍看法是認(rèn)為在細(xì)胞活性停止后(細(xì)胞死亡)ROS消失。固定組織或
細(xì)胞會停止細(xì)胞活性,因此不建議用于ROS檢測。
本品無需固定檢測對象即可檢測到ROS,使用方法包括但不限于將其添加到細(xì)胞培養(yǎng)上清液中或進(jìn)行動物腹腔注射。
