Advanced BioMatrix/Absolute Antibody/Fina Biosolutions厂家答疑

●问题1

货号：5190-7EA

品名：CytoSoft® Discovery Kit

品牌：Advanced BioMatrix

原文：

Q:Can I use acetic acid to dilute and incubate collagen?

A:For applications with CytoSoft, which has a functionalized surface that is sensitive to low pH solutions, you will want to use the CytoSoft directions for use, which indicates neutralizing the collagen acidic solution first and then diluting; 

译文：

问：我可以使用醋酸来稀释并孵育胶原蛋白吗？

答：对于使用 CytoSoft 产品的情况（其表面经过功能化处理，对低 pH 溶液较为敏感），您需要遵循 CytoSoft 的使用说明，其中指出应先将胶原蛋白酸性溶液中和，然后再进行稀释；

●问题2

货号：Ab02746-23.0

品名：Anti-Oxidized phospholipid [E06]

品牌：Absolute Antibody

原文：

Q:What are the recommended dilution ratios for this antibody in ELISA and other applications such as Western blot (WB), immunohistochemistry (IHC), etc., and what diluent should be used?

A:For Ab02746-23.0, we do not have universally recommended dilution ratios for ELISA, Western blot (WB), immunohistochemistry (IHC), or related applications. Optimal working conditions can vary significantly depending on the specific assay setup, target abundance, detection system, and sample type. As such, we generally advise end users to perform a titration to determine the optimal concentration for their specific application.

As a starting point, a typical approach is to test a dilution series (e.g., spanning from ~0.1–10 µg/mL or equivalent serial dilutions, depending on the assay format) and refine based on signal-to-noise performance. I recommend you refer your customer to our FAQ page, specifically to the "At what concentration/dilution should I use my antibody in a particular method?" section.

Regarding diluents, PBS supplemented with a protein carrier (e.g., 1–5% BSA or serum) and a mild detergent (e.g., 0.05% Tween-20) is generally suitable. However, the exact formulation should be aligned with the requirements of the specific assay and detection system.

If you can share further details about the intended application and experimental setup, we would be happy to provide more tailored guidance.

问：该抗体在ELISA、Western blot (WB)、免疫组化 (IHC) 等其他应用中的推荐稀释比例是多少？应使用何种稀释液？

答：关于货号 Ab02746-23.0，我们没有针对 ELISA、Western blot (WB)、免疫组化 (IHC) 或相关应用设定通用的推荐稀释比例。最佳工作条件会因具体的实验设置、靶标丰度、检测系统和样本类型而有显著差异。因此，我们通常建议最终用户通过滴定实验（titration）来确定其特定应用的最佳浓度。

作为起始参考，典型的做法是测试一系列稀释度（例如，根据实验形式涵盖约 0.1–10 µg/mL 或相应的系列稀释），然后根据信噪比表现进行优化。建议您引导客户参阅我们的 FAQ 页面，特别是“在特定方法中，我的抗体应以什么浓度/稀释度使用？"（"At what concentration/dilution should I use my antibody in a particular method?"）这一章节。

关于稀释液，添加蛋白载体（如 1–5% BSA 或血清）和温和去污剂（如 0.05% Tween-20）的 PBS 缓冲液通常适用。不过，具体的配方应根据特定实验和检测系统的要求进行相应调整。

如果您能分享更多关于预期应用和实验设置的详细信息，我们将很乐意提供更具针对性的指导。

●问题3

货号：AD500x100

品名：500 kDa Amino Dextran

品牌：Fina Biosolutions

原文：

Q:Could you please clarify whether the 500kda glucan of this product "AD500x100" is a branched polysaccharide or a linear polysaccharide?

A:Dextran is an α-1,6-glycosidic linked D-glucan with side-chains α-1,3 linked to the backbone units of the Dextran biopolymer. The degree of branching is approximately 5% in native (unfractionated) dextran and decreases with decreasing molecular weight. The branches are mostly 1-2 glucose units long. 

Dextran can be obtained from fermentation of sucrose-containing media by Leuconostoc mesenteroides B512F.

译文：

问：能否请您明确说明该产品‘AD500x100’所含的50万道尔顿葡聚糖是支链多糖还是直链多糖？

答：葡聚糖是一种由 α-1,6 糖苷键连接的 D-葡聚糖，其侧链通过 α-1,3 糖苷键与主链单元相连。在未分级的原生葡聚糖中，其分支度约为 5%，且随着分子量的降低，分支度随之下降。这些侧链大多仅由 1-2 个葡萄糖单元组成。

葡聚糖可通过肠膜明串珠菌（Leuconostoc mesenteroides）B512F 菌株发酵含蔗糖培养基获得。
