The FORMOscreen® buffers are formulated using high-purity chemicals and ultrapure water (>18.0 MΩ) and are sterile-filtered using 0.22 μm filters. No preservatives are added. Prepared at room temperature. Please note that the storage buffer of the target antibody or protein may affect the final pH and/or buffer composition of the buffers. It is thus recommended to work with highly-concentration target antibody or protein stock solutions in order to generate a maximum dilution effect when diluting the target antibody or protein into the buffers.

FORMOscreen® 缓冲液使用高纯度化学品和超纯水 (>18.0 MΩ) 配制而成，并使用 0.22 μm 过滤器进行无菌过滤。 不添加防腐剂。 在室温下制备。 请注意，目标抗体或蛋白质的储存缓冲液可能会影响缓冲液的最终 pH 值和/或缓冲液组成。 因此，建议使用高浓度的目标抗体或蛋白质储备溶液，以便在将目标抗体或蛋白质稀释到缓冲液中时产生最大的稀释效果。

Protocol:
Before using the plate, check the seal for any defects.
1) Let the plate adjust to room temperature.
2) Centrifuge the plate at 300 g for 60 seconds.
3) Carefully remove seal and avoid spilling buffers into adjacent wells.
4) Check all wells for possible precipitations.
In case of visible precipitates, carefully resuspend the respective buffers by pipetting up and down. Buffers in rows G and H and buffer A12 can be more susceptible to precipitation. Ensure proper resuspension before using. In case a 5x-stock solution of a buffer cannot be resuspended completely, dilution of the buffer to its final 1x concentration will ensure proper solving of buffer components. This does not impair buffer quality and the buffer can still be used normally.
5) Prepare the assay samples by diluting your target antibody or protein to the final required assay concentration while also bringing the buffers to 1x final concentration.
Example: Antibody stock concentration 8 mg/mL, required antibody assay concentration 1 mg/mL, final assay volume of 50 μL:
– Mix 10 μL of each 5x buffer stock with 33.75 μL ultrapure water
– Add 6.25 μL antibody
– The antibody will then be at 1 mg/mL in the final 1x buffer
6) Alternatively, in order to generate 1x buffer solutions, dilute the 5x stocks 1:5 in ultrapure water, e.g. mix 100 μl of 5x stocks with 400 μl ultrapure water and mix carefully to get 500 μl 1x buffer solutions.

协议：
在使用板之前，请检查密封是否有任何缺陷。
1）让盘子调整到室温。
2) 将板以 300 g 离心 60 秒。
3) 小心取下密封，避免将缓冲液溢出到相邻的孔中。
4) 检查所有孔是否有可能的沉淀。
如果出现可见沉淀，请通过上下移液小心地重新悬浮相应的缓冲液。 G 行和 H 行中的缓冲液以及缓冲液 A12 可能更容易受到沉淀的影响。使用前确保适当的再悬浮。如果缓冲液的 5x 储备溶液不能完全重新悬浮，将缓冲液稀释至最终 1x 浓度将确保缓冲液组分的正确溶解。这不会影响缓冲液质量，缓冲液仍可正常使用。
5) 通过将目标抗体或蛋白质稀释至最终所需的检测浓度来制备检测样品，同时使缓冲液达到最终浓度的 1 倍。
示例：抗体储备浓度 8 mg/mL，所需抗体测定浓度 1 mg/mL，最终测定体积 50 μL：
– 将 10 μL 的每个 5x 缓冲液与 33.75 μL 超纯水混合
– 添加 6.25 μL 抗体
– 最终 1x 缓冲液中的抗体浓度为 1 mg/mL
6) 或者，为了生成 1x 缓冲溶液，在超纯水中以 1:5 稀释 5x 库存，例如将 100 μl 的 5x 原液与 400 μl 超纯水混合，并仔细混合以获得 500 μl 1x 缓冲溶液。

Q: Why do I have to resuspend the buffers before use?
A: The plate provides high-concentration buffer stocks (5x) in order to enable a variety of measurements for the customer. Due to the high stock concentration, some components may precipitate over time. In order to avoid inaccuracy during measurements, resuspend the 5x buffer stock solutions by pipetting up and down. After proper resuspension, there are no negative effects from any precipitates.

Q: How many samples can be analyzed with one plate?
A: Depending on the applied analysis method, the plate can serve for many experiments. The plate contains 230 μl of 5x stock solutions, so theoretically 1.15 ml of 1x buffers can be prepared.

Q: Is it possible to purchase individual buffers?
A: Yes, individual buffers can be purchased. Please contact us
