產品詳情

詳細信息(中文)：
瓊脂糖商品名很多，常見的有，Sepharose（瑞典，pharmacia ），Bio-Gel-A（美國Bio-Rad）等。瓊脂糖凝膠是依靠糖鏈之間的次級鏈如氫鍵來維持網狀結構，網狀結構的疏密依靠瓊脂糖的濃度。一般情況下，它的結構是穩(wěn)定的，可以在許多條件下使用（如水，pH4-9范圍內的鹽溶液）。瓊脂糖凝膠在40℃以上開始融化，也不能高壓消毒，可用化學滅菌活處理。
瓊脂糖 Agarose，縮寫為AG，是瓊脂中不帶電荷的中性組成成份，也譯為瓊膠素或瓊膠糖。瓊膠糖化學結構由β-D-吡喃半乳糖(1-4)連接3,6-脫水α-L-吡喃半乳糖基單位構成.
把瓊脂糖，即幾乎不含硫酸根的主要成分為多糖的瓊脂，溶于熱水，冷卻制成的凝膠。制成的小顆粒用于凝膠過濾。適于用sephadex不能分級分離的大分子的凝膠過濾，若使用5%以下濃度的凝膠，也能夠分級分離細胞顆粒、病毒等。利用其吸附性小的特點，有時用它代替瓊脂、以作為免疫電泳或凝膠內沉降反應的支持物。

詳細信息(英文)：
There are many trade names, such as Sepharose (Sweden, Pharmacia), bio gel-a (US bio RAD), etc. Agarose gel relies on secondary chains such as hydrogen bonds to maintain the network structure. The density of the network depends on the concentration of agarose. In general, its structure is stable and can be used under many conditions (such as water, salt solution in the range of ph4-9). Agarose gel begins to melt at more than 40 degrees and can not be sterilized by high pressure. It can be treated by chemical sterilization.

Agarose, abbreviated as Ag, is a neutral component of agar without charge. It is also translated as agarose or agarose. The chemical structure of agarose consists of β - D-galactopyranosyl (1-4) linked 3,6-dehydrated α - l-galactopyranosyl units

Agarose, which is almost the main component of the sulfate free polysaccharide, is a polysaccharide agar dissolved in hot water and cooled to make the gel. Small particles made are used for gel filtration. It is suitable for gel filtration of macromolecules which can not be fractionated by Sephadex. If the gel is less than 5%, it can also be used for fractionation of cell particles and viruses. It is sometimes used instead of agar as a support for immune electrophoresis or gel sedimentation reaction because of its small adsorption characteristics.
