本慢病毒溶解缓冲液为优化配比配方,以 HEPES‑碳酸氢钠作为缓冲基础,添加 L‑谷氨酰胺、微量元素与冻存保护剂。可用于超速离心、PEG 沉淀、超滤浓缩所得慢病毒沉淀的重悬;重悬后的慢病毒颗粒毒性低,储存稳定性佳,能够耐受多次冻融,适配多种慢病毒实验应用。
使用说明:
超离、PEG 沉淀后的病毒重悬
1、 根据预期的浓缩倍数,加入适量的慢病毒溶解缓冲液(例如 100 mL 慢病毒原液预期浓缩 100 倍,则要加入1 mL 慢病毒溶解缓冲液),然后通过移液器轻轻吹打沉淀;
2、 静置 4~6 h,让沉淀中的慢病毒颗粒释放到慢病毒溶解缓冲液中;
3、 于 4℃以 11,200 ×g(~12,000 rpm*)离心 3 min,收集上清液,以合适体积分装冻存于-80℃低温冰箱中。
*为约 7 cm 有效离心半径的小离心机换算(≤2 mL 离心管)。
超滤浓缩后的 buffer 置换
慢病毒原液经超滤离心后,加入适量慢病毒溶解缓冲液,离心至所需要的体积,分装冻存于-80℃低温冰箱中。

This Lentiviral Solution Buffer adopts an optimized formulation based on the HEPES‑sodium bicarbonate buffering system, supplemented with L‑glutamine, trace elements and cryoprotectants. It is used for resuspending lentiviral pellets obtained from ultracentrifugation, PEG precipitation and ultrafiltration concentration. Lentiviral particles resuspended in this buffer show low cytotoxicity, good storage stability and tolerance to multiple freeze‑thaw cycles, and are suitable for various lentivirus‑related experiments.
Instructions for Use
Resuspension of virus pellets after ultracentrifugation or PEG precipitation
1. Add an appropriate volume of Lentiviral Solution Buffer according to the expected concentration factor (e.g., for 100 mL original lentivirus stock expected to be concentrated 100‑fold, add 1 mL of Lentiviral Solution Buffer), then gently pipette up and down to resuspend the pellet.
2. Allow the mixture to stand for 4‑6 h to enable lentiviral particles in the pellet to be released into the Lentiviral Solution Buffer.
3. Centrifuge at 11,200 × g (~12,000 rpm*) for 3 min at 4 °C. Collect the supernatant, aliquot it into suitable volumes and store at −80 °C.
*Conversion for small‑volume centrifuge with approximately 7 cm effective rotor radius (for ≤2 mL centrifuge tubes).
Buffer exchange after ultrafiltration concentration
After ultrafiltration of the original lentivirus stock, add an appropriate amount of Lentiviral Solution Buffer, perform centrifugation until the target volume is reached, aliquot and store at −80 °C.
