General description
琼脂含有琼脂糖和琼脂果胶，其中琼脂糖是主要的胶凝杂多糖。琼脂糖含有β-d-半乳糖和3,6-脱水-α-L-半乳糖，通过名为新琼脂糖的糖苷键β(1-4)连接。其中還含有具有相同双糖单元及α(1-3)连接的琼脂二糖。琼脂的主要来源是红藻科的海藻细胞壁。
Application
琼脂已作为EDMm（桉基培养基改性版）的成分，用于对桉无性系枝条的发育进行研究。它也被用作球形枝孢霉TC09菌株离体培养的Murashige和Skoog培养基的成分。
琼脂已被用作以下组分
- Gamborg′s再生培养基
- Murashige and skoog (Ms)培养基，用于诱导三棱三叶金丝桃种子发芽三棱三叶金丝桃种子发芽
- 用来再生拟南芥幼苗的靶向诱导和萘乙酸预处理培养基
Biochem/physiol Actions
琼脂主要用作微生物固体培养基。它的使用浓度范围为0.5到1.0％(w/v)，可用于固化植物组织培养基。这对于体外根系发育至关重要。
Preparation Note
常见工作浓度： 6-12 g/L。
Other Notes
专用于研究和原生质体培养纯化。
