PEG Virus Precipitation Kit

產品描述：病毒通常以低力價產生。Biovision提供低速簡單之方法，濃縮病毒力價和去除雜質，。PEG病毒沉澱試劑盒簡單，方便和省時，可以將病毒濃縮而無需超離心。 該試劑盒可用於小實驗室樣品或大規模病毒製備，產量高，病毒滴度高。 該試劑盒可用於將細胞培養基或環境樣品中的逆轉錄病毒(retroviruses)，桿狀病毒(baculoviruses)，慢病毒(baculoviruses)和噬菌體(lentiviruses)等進行濃縮。 病毒可以集中在100倍以上。 根據病毒類型和來源，提供優化的病毒再懸浮液，使病毒恢復最大化達40-100％。整個過程使用無毒試劑，濃縮病毒可用於感染，病毒DNA或RNA純化等應用。Virus was usually produced at a low titer. It often needs to be concentrated for storage or further applications. A quick, easy and inexpensive method is desired to concentrate virus and remove impurities. BioVision’s PEG Virus Precipitation Kit provides an easy, convenient and time-saving method to concentrate virus without ultra-centrifugation. The kit can be used for small lab samples or large scale virus preparation with high yield and high viral titer. The kit can be used to concentrate retroviruses, baculoviruses, lentiviruses, and phages etc. in cell culture medium or environmental samples. Virus can be concentrated over 100 folds. An optimized Virus Re-suspension Solution is provided to maximize viral recovery by 40-100% depending on the virus type and sources. The whole process uses non-toxic reagents. The concentrated virus can be used for infection, viral DNA or RNA purification, etc.

a) 對於高滴度病毒製劑，重懸體積應限制在白色沉澱體積的三倍左右，通常為原始樣品體積的 1/10 至 1/100。如果病毒懸浮液中存在不溶性物質，可透過在 +4°C 下以 3,200 x g 離心 15 分鐘將其去除。

b) 避免冷凍/解凍循環以最大限度地提高病毒恢復率。

c) 病毒懸浮液中微量的PEG不會影響濃縮病毒的使用。在某些情況下，PEG可能會提高病毒感染效率。然而，如果需要，可以透過以下步驟去除微量的 PEG：

將 1 體積的含有 4 M KCl 和 50 mM Tris-HCl，pH7.2（未提供）的溶液加入 3 體積的濃縮病毒懸浮液中。或者，將固體 KCl 加入病毒懸浮液中，直到終濃度為 1 M。在冰上靜置 15-30 分鐘。在 4°C 下以 12,000 x g 旋轉 10 分鐘以除去沉澱物。小心收集病毒上清液。等分並儲存於 -80°C 以備將來使用。
