| 背景介绍 | FGF-basic is a members of the Fibroblast Growth Factors (FGFs) family. The family constitutes a large family of proteins involved in many aspects of development including cell proliferation, growth, and differentiation. They act on several cell types to regulate diverse physiologic functions including angiogenesis, cell growth, pattern formation, embryonic development, metabolic regulation, cell migration, neurotrophic effects, and tissue repair. FGF-basic is a non-glycosylated heparin binding Growth Factor that is expressed in the brain, pituitary, kidney, retina, bone, testis, adrenal gland liver, monocytes, epithelial cells and endothelial cells. FGF-basic signals through FGFR 1b, 1c, 2c, 3c and 4. |

Q1:官网的因子都是不含动物成分的么？
我们公司的因子都是重组的，是不含动物源成分的。
-
Q2:细胞因子用无菌水配成了100ug/mL母液，用于实验时，需要的终浓度为10ng/mL，可以用培养基直接稀释？还是需要通过PBS（含5%海藻糖）进一步稀释才行呢？
如果是直接做实验，可以直接添加培养基进行稀释配置。 如果是需要长时间保存的话，需要使用含载体蛋白(如0.1%BSA，10% FBS，5%HSA或5%海藻糖)的溶液进一步释后分装保存于-5~-20℃或者-80℃冰箱
-
Q3:细胞因子加无菌水溶解后需要再次离心吗？
加了无菌水后，如果没有挂壁现象是不用离心的，如果您放置了一段时间，再次使用时是可以使用离心机离心的
-
Q4:细胞因子离心前需要放置室温吗？
不用提前放置室温.
-
Q5:收到细胞因子产品用什么溶剂复融？
1、细胞因子产品大部分为冻干形式发货，少部分液体形式发货； 2、冻干粉状态的因子产品需指定溶剂复溶，请参考产品说明书【复融】方法，按照要求使用对应溶剂溶解，大部分因子为无菌水复融，少部分需要无菌水以外的特殊溶剂溶解的产品则随货会赠送相应的复融试剂；冻干粉溶解后如您需要进一步稀释分装，需使用含载体蛋白(如0.1% BSA，10%FBS，5%HSA 或 5% 海藻糖)的溶液进一步稀释后分装冷冻保存。 3、液体形式因子产品不需要复溶，具体浓度详见产品标签，按照实验需要用含载体蛋白(如0.1% BSA，10%FBS，5%HSA 或 5% 海藻糖)的溶液进一步稀释后分装冷冻保存即可；
