一般描述

磷酸盐缓冲液是手术灌洗液的最常用组分，用于保存活组织。它也用于免疫化学染色流程。磷酸盐缓冲液是光学和电子显微镜的重要固定剂。其缓冲能力对pH敏感，最好在生理pH（7.2-7.4）下使用。[1]

应用

适合用作各种Romanowsky型染色流程的缓冲液，包括Wright Stain、Wright Giemsa、Giemsa、May Grunwald、Jenner和Leishman。在25℃下pH 7.2的磷酸盐缓冲液已被用于收集猪卵巢的卵母细胞。[2]

重悬

每瓶可制备3.8 L缓冲液，8.3 mM。

Questions

1–4 of 4 Questions  

  1. could you provide me with the Wright-Giemsa protocol referenced in the question above about how to solubilize Product P3288, Phosphate Buffer pH 7.2. We need official instructions for use and the product did not come with it.

    1 answer

    1. If this product is ordered separately, no instructions are provided. Instructions for preparing P3288 are found in the WG Instructions for Use that ship with each bottle of WG16, WG32, WG80, or WG128. Below is the information from the Reagent section of the WG procedure Instructions For Use

      The phosphate buffer should be prepared by diluting 1 vial of buffer to 1 gallon or 3.8 liters of deionized water. Mix well to dissolve. Discard the working phosphate solution if turbidity or visible bacterial growth is present. Store the working phosphate buffer solution at 2-8°C

      Helpful?

  2. Once made how long is the solution good for?

    1 answer

    1. The long term stability of this product in solution has not been evaluated. Upon reconstitution, the solution should be observed for any particulate matter or turbidity which would indicate possible microbial growth. However, similar prepared solutions such as P3619, a 1M Phosphate Buffer, are not assigned an expiration date. These products are quite stable and offer a warranty of 1 year from the date of shipment.
