    PF and BAI combination suppresses activation of the NF-κB signaling pathway in LPS-treated HOKs. Western blotting assay is performed to investigate expression of NF-κB inflammatory signaling proteins.

    Baicalin purchased from MCE. Usage Cited in: Oral Dis. 2019 Nov;25(8):1945-1953.  [Abstract]

    The nuclear translocation of NF-κB p65 was visualized using a laser confocal scanning microscope imaging system. Nuclei detected with DAPI (blue). Cells expressing NF-κB p65 in the cytoplasm (green). NF-κB p65 expresses mostly in the nucleus, and a small amount expressed in the cytoplasm (green). Localization of NF-κB p65 in the cytoplasm (green).

    Baicalin 通過(guò)改變各種介質(zhì)的產(chǎn)生來(lái)防止缺血再灌注損傷 (IRI),這些介質(zhì)包括活性氧 (ROS)、Toll 樣受體 (TLR) 2 和 TLR4、NF-κB、Bax 和 Bcl-2。Baicalin 處理抑制促炎細(xì)胞因子TLR2/4、MyD88、p-NF-κB和p-IκB的表達(dá)增加,以及增加NF-κB抑制劑IκB蛋白的表達(dá)[1]。
    細(xì)胞活力通過(guò) MTT 測(cè)定法確定。與對(duì)照細(xì)胞相比,用凝血酶處理的 SH-SY5Y 細(xì)胞的細(xì)胞活力顯著降低。與單獨(dú)使用凝血酶處理的細(xì)胞相比,用 Baicalin (5,10,20 μM) 預(yù)處理以劑量依賴(lài)的方式增加細(xì)胞活力[2]。

    Cell Assay
    [2]

    SH-SY5Y cell lines are cultured in RPMI-1640 medium supplemented with 15% fetal bovine serum at 37°C in an air atmosphere containing 95% air and 5% CO2 with a saturated humidity. Upon a confluence of 60~70%, the SH-SY5Y cells are divided into: (i) control group, incubated in RPMI-1640 medium; (ii) thrombin group, which is subject to thrombin induction (40 U/L) for 6 h based on our pre-experiment; and (iii) Baicalin groups, which are treated by Baicalin (5 μM, 10 μM, or 20 μM) for 2 h before induction of thrombin. Cell viability is measured using MTT assay. Briefly, 15 μL of the MTT solution (5 mg/mL) is added to each well and incubated for 4 h at 37°C. After removing the supernatant, 80 μL DMSO are added into each well. The absorbance is measured at 492 nm using a microplate reader. All experiments are performed in triplicate[2].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration
    [1]

    Rats[1]
    Male Wistar rats weighing 200-250 g are used. Rats are randomly divided into five groups of six rats each: (i) sham group; (ii) IR+saline group; (iii) IR+Baicalin (1 mg/kg) group; (iv) IR+Baicalin (10 mg/kg) group; and (v) IR+Baicalin (100 mg/kg) group. Renal IRI is induced by clamping the left renal artery for 45 min plus a right nephrectomy. Rats are anesthetized through an intraperitoneal injection of pentobarbital sodium (40 mg/kg body weight). After a median abdominal incision, the left renal arteries are clamped for 45 min with serrefine. After clamp removal, adequate restoration of blood flow is checked before abdominal closure. The right kidney is then removed. Sham-operated animals underwent the same surgical procedure without clamping[1].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
