生物活性

Gadopentetate dimeglumine (SH-L-451A) is used in combination with magnetic resonance imaging (MRI) to allow blood vessels, organs, and other non-bony tissues to be seen more clearly on the MRI.

体外研究
(In Vitro)

Gadobenate dimeglumine-enhanced MRI significantly improves cancer detection compared to gadopentetate dimeglumine-enhanced MRI, mammography, and ultrasound in a selected group of patients undergoing breast MRI for preoperative staging or because of inconclusive findings at conventional imaging[1]. Interstitial MR lymphography with gadopentetate dimeglumine (Gd-DTPA) or gadoxetate disodium (Gd-EOB-DTPA) allows clear visualization of the lymphatic pathway in healthy mice, and no significant difference is found between the two agents. Their rapid kinetics limits the imaging timing window, however, facilitates repeated assessment in a single imaging session[2]. Direct visualization of spilled gastrointestinal gadopentetate dimeglumine helps discriminate ischemic from control rats in this model[3].

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

请根据您的 实验动物和给药方式 选择适当的溶解方案。

以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

  • 方案 一

    请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (2.67 mM); 澄清溶液

    此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

    生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。
  • 方案 二

    请依序添加每种溶剂: 10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (2.67 mM); 澄清溶液

    此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中,混合均匀。

    20% SBE-β-CD in Saline 的配制(4°C,储存一周):2 g SBE-β-CD(磺丁基醚 β-环糊精)粉末定容于 10 mL 的生理盐水中,完全溶解至澄清透明。

以下溶解方案,请直接配置工作液。建议现用现配,在短期内尽快用完。 以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比; 如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶。

Animal Administration
[2][3]

Rats: Twenty-eight rats are anesthetized and midline laparotomy is performed. Animals are divided into four groups: control, ligation of a single mesenteric arcade, ligation of six consecutive arcades, and ligation of the anterior mesenteric artery (analogous to the superior mesenteric artery in humans). A 1.0-mL enteric bolus of gadopentetate dimeglumine diluted with sterile water (1:1) is given via gavage. Magnetic resonance imaging is performed 2 hr after laparotomy and reviewed for the presence of intraperitoneal gadopentetate dimeglumine by two experienced observers. Animals are sacrificed 24 hr after surgery for pathologic examination[3].

Mice: MR lymphography are performed after the subcutaneous injection of gadopentetate dimeglumine (Gd-DTPA) or gadoxetate disodium (Gd-EOB-DTPA) (0.1, 0.5, or 2.0 mmol per mouse) into the right footpad in six healthy mice, and the time courses of contrast enhancement are assessed. Additionally, the lymphatic pathways from two distinct sites are assessed in tandem by interstitial MR lymphography studies[2].

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.
