SEQUENCE of the Recombinant Fibroblast Growth Factor 4 (FGF4)

USAGE of the Recombinant Fibroblast Growth Factor 4 (FGF4)
Reconstitute in 20mM Tris, 150mM NaCl (pH8.0) to a concentration of 0.1-1.0 mg/mL. Do not vortex.
STORAGE of the Recombinant Fibroblast Growth Factor 4 (FGF4)
Avoid repeated freeze/thaw cycles. Store at 2-8°C for one month. Aliquot and store at -80°C for 12 months.
STABILITY of the Recombinant Fibroblast Growth Factor 4 (FGF4)
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37°C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.

基因重组只是控制同一性状表达不同而已,但是它不会改变性状的基本情况。如:控制眼睛颜色的基因,亲本的基因重组之后可能亲本为黑色,子代便为蓝色。但绝对不会控制眼睛颜色的基因在重组之后就变成控制耳朵的基因。

考研细胞的题答案
你可以试着读一下看看。
或者可以过柱纯化,过柱纯化要加一半的佐剂,所以纯化后浓度要高于500ug/ml为宜,否则要增加免疫的次数。
生物制品细胞制备过程中不得使用青霉素或β-内酰胺(β-Lactam)类抗生素,明确表明不准使用青霉素。那么进行的重组蛋白类表达的微生物发酵,可以用青霉素吗?
2、2015版药典三部,各论中指出,”将检定合格的工作种子批菌种接种于适宜培养基(可含适量抗生素)中培养“,”发酵用培养基(采用适宜的不含抗生素的培养基)“。
这里说明种子培养基中可以使用抗生素,而且也没有限定究竟是哪种抗生素。
3、关于发酵中使用的抗生素,不知大家一般用哪家的,一些常用的,氨苄西林钠,硫酸卡那霉素,氯霉素等,都是用的什么级别,那个厂家的呢?我现在生工的,阿拉丁的,生兴生物的都用过。主要还是用的生工生物的,但是生工生物的抗生素都是进口分装的,不仅仅抗生素,国内很多进口分装的试剂,都无法提供相应的产品质量检测证书。而且因为是分装的,基本也就属于只有销售,所以,以后真的生产了,原材料来源的稳定性也无法保证。请问这个问题,大家是怎么解决的,一般用的哪家的呢。
