The serum contains flocculent precipitates — what are they and how should they be handled? Recently, a sophomore student named Wang Yu conducted an experiment and noticed some strange particles in the serum. He reached out to us for assistance.
Based on our extensive experience, these precipitates are typically composed of fibrin or lipoproteins — both are natural components of serum and do not affect the quality or performance of the product. To remove them, you can either centrifuge the serum at 400g for 1-2 minutes or let it settle naturally. After that, carefully transfer the serum into a new sterile vial. It's generally not recommended to filter the serum, as the precipitate may clog the filter and reduce its effectiveness.
In most cases, gently shaking the serum and warming it to 37°C will help dissolve the precipitate. Therefore, when using the product, we recommend shaking the serum and heating it to 37°C before use — the sediment should disappear naturally.
We appreciate your trust in Shanghai Jinma Bio. If you have any more questions or need further assistance, feel free to contact us. Happy shopping and best of luck with your experiments!
