MB000102-R70170 (or MB102)：Syd Labs D-荧光素钾盐(D-Luciferin Potassium Salt)

Syd Labs D-荧光素钾盐（别称：D-萤光素钾盐、D-虫荧光素钾盐）的质量和性能已经被数百篇引用文献所证实（后续还将不断补充）:

1.Imaging CRISPR-edited CAR-T cell therapies with optical and positron emission tomography reporters
Sanchez-Pupo RE,et al.Theranostics. 2026 Jan 1;16(7):3227-3245. doi: 10.7150/thno.119013. PMID: 41608579; PMCID: PMC12846014

原文片段1：“In vitro BLI and cytotoxicity assays：Seven days after nucleofection, CAR-T cell cytotoxicity was assessed by co-incubating CAR-T cells with firefly luciferase (Fluc)-expressing target cancer cells and measuring BLI over time. Briefly, 1.25 x 104 target cells/well were plated in 96-well plates in 100 μL of serum-supplemented culture media. T cells were then added at various effector-to-target ratios (0.5:1, 1:1, 2:1, or 4:1). The plate was incubated for 18-24 h at 37 °C, 5% CO2. BLI was acquired with an IVIS Lumina XRMS In Vivo Imaging System (PerkinElmer) after adding D-luciferin (150 μg/mL, Syd Labs) to each well. Regions of interest (ROI) were drawn over each well to quantify the peak average radiance per well (photons(p)/second(s)/cm2/steradian(sr)). BLI data analysis was conducted using the Living Image Software (PerkinElmer). ”

原文片段2：“In vivo Bioluminescence Imaging (BLI): Mice were anesthetized with 1-2% isoflurane and imaged using an IVIS Lumina XRMS system (Revvity) following IP injection of BLI substrates: Akalumine-HCl (Sigma-Aldrich, Cat#808350-5MG) (5 mM, 100 μL), D-luciferin (Syd Labs, Cat#MB000102-R70170) (150 µg/mL, 100 μL), Nano-Glo FFZ (Promega, Cat#N4100) (2.3 mM, 50 μL) to track AkaLuc-, FLuc- or Antares-expressing cells, respectively. Images were acquired every 2 min for up to 30 min or until peak radiance was reached. Dual AkaLuc (CAR-T) and Antares (cancer cells) imaging was spaced 1-2 days apart to avoid residual bioluminescence overlap.“

2.CAR macrophages with built-In CD47 blocker combat tumor antigen heterogeneity and activate T cells via cross-presentation
Siqi Chen,et al.Nat Commun. 2025.PMCID: PMC12043996
原文片段：“Bioluminescence imaging：Bioluminescent imaging was performed on a Lago X instrument (Spectral Instruments Imaging). Mice were intraperitoneally injected with D-luciferin (140 mg/kg; #MB000102-R70170, Syd labs) and then anesthetized by 2–3% isoflurane inhalation. Mice were imaged inside the camera box with continuous exposure to isoflurane. For the efficacious experiments, data was acquired using binning 16, and exposure 1 s as default; For macrophages in vivo distribution and longevity, data was acquired using binning 16 and exposure 120 s. Data were analyzed with Aura software (Spectral Instruments Imaging) where regions of interest were drawn and quantified as photons per second.”

3.The impact of a high fat diet and platelet activation on pre-metastatic niche formation
Marta Hergueta-Redondo,et al.Nat Commun. 2025.PMCID: PMC11965330
原文片段：“Experimental metastasis assay：To investigate the effects of a HFD on experimental metastasis to the lungs, 1×105 EO771 BC cells labeled with GFP and luciferase (GFP-Luc) were injected into the tail vein of 22-week-old male and female DIO mice. Cells were resuspended in calcium- and magnesium-free PBS, and filtered through a 40 μm mesh immediately prior to injection. Animals were injected with luciferin (3 mg: MB102, syd labs), and lung metastases were then analyzed by bioluminescent imaging (Xenogen IVIS-200 Optical In Vivo Imaging System) 1 h, 24 h, 2 or 5 weeks after tumor cell injection using Living Image 4.7.2 software (PerkinElmer).”

D-荧光素储备溶液和工作溶液如何制备:

体外生物发光试验（in vitro bioluminescent assay）：在无菌去离子水中制备200x D-荧光素储备溶液 (30 mg/ml)。通过倒置轻轻混合，直到化学物质完全溶解。在预热培养基中制备最终浓度为150 μg/ml的D-荧光素工作溶液。

体内成像（in vivo imaging）：在 DPBS 中制备15 mg/ml的D-荧光素储备溶液。通过倒置轻轻混合，直至化合物完全溶解。过滤器通过0.2微米的过滤器对溶液进行消毒。以10μL/g体重确定注射量。每只小鼠接受150 mg D-荧光素钾盐/kg体重，如对于体重为10 g的小鼠，需要注射100 μL以提供1.5 mg D-荧光素（D-luciferin）。

D-荧光素钾盐的pH稳定性:

如果 pH > 6.3，它可以通过缓慢外消旋转化为 L-荧光素。

D-荧光素钾盐在粉末和溶液中的储存：

在紫外线和/或潮湿条件下，它可能会形成脱氢荧光素。冻干粉应避光-20°C储存。对于体内和体外使用，用 PBS 或去离子水重组后的原液，可在4°C下避光储存3周，在-20°C下储存3个月。

Syd Labs D-荧光素钾盐相关问答:

问: 你们提供d-荧光素钾盐免费样品吗？

答: 抱歉，我们不提供免费样品。您可以直接下单，我们会为您保留发票，直到您确认满意我们的产品“D-荧光素钾盐”。如果您对产品不满意，无需支付任何费用。这是一种免费样品的替代方案。

问: 你们的d-萤光素钾盐可以注射到动物体内，比如小鼠体内吗？

答: 可以。在动物体内注射前，需要对d-荧光素溶液进行过滤消毒。我们的大多数客户使用d -荧光素钾盐进行体内成像，如上面的参考文献所述。

问: D-荧光素钾盐可溶于水吗?

答: D-荧光素钾盐是水溶性的，尽管D-荧光素钾盐的水溶性比D-荧光素钠盐低。

问: D-荧光素钾盐的pH稳定性如何?

答: D-荧光素钾盐最佳pH值为6.0至6.3。如果pH值大于6.3，D-荧光素钾盐可能会通过缓慢的消旋作用转化为L-荧光素，从而竞争性地抑制荧光素酶催化D-荧光素产生发光反应。由于大多数客户使用水或DPBS溶解D-荧光素时未调节pH值，因此溶液应储存在-20°C，并尽量在3个月内使用。
