背景介紹 | Fibroblast Growth Factors (FGFs) comprise a family of at least eighteen structurally related Proteins that are involved in a multitude of physiological and pathological cellular processes, including cell growth, differentiation, angiogenesis, wound healing and tumorgenesis. The biological activities of the FGFs are mediated by a family of type I transmembrane tyrosine kinases which undergo dimerization and autophosphorylation after Ligand binding. Four distinct genes encoding closely related FGF Receptors, FGF R1-4, are known. All four genes for FGF Rs encode Proteins with an N-terminal signal peptide, three immunoglobulin (Ig)-like domains, an acid-box region containing a run of acidic residues between the IgI and IgII domains, a transmembrane domain and the split tyrosine-kinase domain. Multiple forms of FGF R1-3 are generated by alternative splicing of the mRNAs. A frequent splicing event involving FGF R1 and 2 results in Receptors containing all three Ig domains, referred to as the α isoform, or only IgII and IgIII, referred to as the β isoform. Only the α isoform has been identified for FGF R3 and FGF R4. Additional splicing events for FGF R1-3, involving the C-terminal half of the IgIII domain encoded by two mutually exclusive alternative exons, generate FGF Receptors with alternative IgIII domains (IIIb and IIIc). The complex patterns of expression of these Receptors as well as the specificity of their interactions with the various FGF Ligand family members are under investigation. |

Q2:細(xì)胞因子用無(wú)菌水配成了100ug/mL母液,用于實(shí)驗(yàn)時(shí),需要的終濃度為10ng/mL,可以用培養(yǎng)基直接稀釋?zhuān)窟€是需要通過(guò)PBS(含5%海藻糖)進(jìn)一步稀釋才行呢?
如果是直接做實(shí)驗(yàn),可以直接添加培養(yǎng)基進(jìn)行稀釋配置。 如果是需要長(zhǎng)時(shí)間保存的話,需要使用含載體蛋白(如0.1%BSA,10% FBS,5%HSA或5%海藻糖)的溶液進(jìn)一步釋后分裝保存于-5~-20℃或者-80℃冰箱
-
Q3:細(xì)胞因子加無(wú)菌水溶解后需要再次離心嗎?
加了無(wú)菌水后,如果沒(méi)有掛壁現(xiàn)象是不用離心的,如果您放置了一段時(shí)間,再次使用時(shí)是可以使用離心機(jī)離心的
-
Q4:細(xì)胞因子離心前需要放置室溫嗎?
不用提前放置室溫.
-
Q5:收到細(xì)胞因子產(chǎn)品用什么溶劑復(fù)融?
1、細(xì)胞因子產(chǎn)品大部分為凍干形式發(fā)貨,少部分液體形式發(fā)貨; 2、凍干粉狀態(tài)的因子產(chǎn)品需指定溶劑復(fù)溶,請(qǐng)參考產(chǎn)品說(shuō)明書(shū)【復(fù)融】方法,按照要求使用對(duì)應(yīng)溶劑溶解,大部分因子為無(wú)菌水復(fù)融,少部分需要無(wú)菌水以外的特殊溶劑溶解的產(chǎn)品則隨貨會(huì)贈(zèng)送相應(yīng)的復(fù)融試劑;凍干粉溶解后如您需要進(jìn)一步稀釋分裝,需使用含載體蛋白(如0.1% BSA,10%FBS,5%HSA 或 5% 海藻糖)的溶液進(jìn)一步稀釋后分裝冷凍保存。 3、液體形式因子產(chǎn)品不需要復(fù)溶,具體濃度詳見(jiàn)產(chǎn)品標(biāo)簽,按照實(shí)驗(yàn)需要用含載體蛋白(如0.1% BSA,10%FBS,5%HSA 或 5% 海藻糖)的溶液進(jìn)一步稀釋后分裝冷凍保存即可;
