●問題1

貨號：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; 

譯文：

問：我可以使用醋酸來稀釋并孵育膠原蛋白嗎？

答：對于使用 CytoSoft 產(chǎn)品的情況（其表面經(jīng)過功能化處理，對低 pH 溶液較為敏感），您需要遵循 CytoSoft 的使用說明，其中指出應(yīng)先將膠原蛋白酸性溶液中和，然后再進行稀釋；

●問題2

貨號：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.

譯文：

問：該抗體在ELISA、Western blot (WB)、免疫組化 (IHC) 等其他應(yīng)用中的推薦稀釋比例是多少？應(yīng)使用何種稀釋液？

答：關(guān)于貨號 Ab02746-23.0，我們沒有針對 ELISA、Western blot (WB)、免疫組化 (IHC) 或相關(guān)應(yīng)用設(shè)定通用的推薦稀釋比例。最佳工作條件會因具體的實驗設(shè)置、靶標豐度、檢測系統(tǒng)和樣本類型而有顯著差異。因此，我們通常建議最終用戶通過滴定實驗（titration）來確定其特定應(yīng)用的最佳濃度。

作為起始參考，典型的做法是測試一系列稀釋度（例如，根據(jù)實驗形式涵蓋約 0.1–10 µg/mL 或相應(yīng)的系列稀釋），然后根據(jù)信噪比表現(xiàn)進行優(yōu)化。建議您引導客戶參閱我們的 FAQ 頁面，特別是“在特定方法中，我的抗體應(yīng)以什么濃度/稀釋度使用？"（"At what concentration/dilution should I use my antibody in a particular method?"）這一章節(jié)。

關(guān)于稀釋液，添加蛋白載體（如 1–5% BSA 或血清）和溫和去污劑（如 0.05% Tween-20）的 PBS 緩沖液通常適用。不過，具體的配方應(yīng)根據(jù)特定實驗和檢測系統(tǒng)的要求進行相應(yīng)調(diào)整。

如果您能分享更多關(guān)于預(yù)期應(yīng)用和實驗設(shè)置的詳細信息，我們將很樂意提供更具針對性的指導。

●問題3

貨號：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.

譯文：

問：能否請您明確說明該產(chǎn)品‘AD500x100’所含的50萬道爾頓葡聚糖是支鏈多糖還是直鏈多糖？

答：葡聚糖是一種由 α-1,6 糖苷鍵連接的 D-葡聚糖，其側(cè)鏈通過 α-1,3 糖苷鍵與主鏈單元相連。在未分級的原生葡聚糖中，其分支度約為 5%，且隨著分子量的降低，分支度隨之下降。這些側(cè)鏈大多僅由 1-2 個葡萄糖單元組成。

葡聚糖可通過腸膜明串珠菌（Leuconostoc mesenteroides）B512F 菌株發(fā)酵含蔗糖培養(yǎng)基獲得。
