| 制劑 | Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. |
| 復(fù)融 | Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in sterile water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. |
| 背景介紹 | Mouse CCL24 is a secreted Protein, which is a member of the CC Chemokine subfamily. Mouse Ccl24 cDNA encodes a 119 amino acid residue precursor Protein, shares approximately 58% amino acid sequence identity with human Ccl24. It is predominantly expressed in the jejunum and spleen and also be induced in the lung by allergen challengeand IL4. Mouse ccl24 has lower chemotactic activity for neutrophils but none for monocytes and activated lymphocytes. Ccl24 is chemotactic for resting T-lymphocytes, eosinophils and can bind to CCR3. LPS and IL4 also differentially regulate the expression of Ccl24 in monocytes and macrophages. |

Q1:官網(wǎng)的因子都是不含動物成分的么？
我們公司的因子都是重組的，是不含動物源成分的。

Q2:細(xì)胞因子用無菌水配成了100ug/mL母液，用于實驗時，需要的終濃度為10ng/mL，可以用培養(yǎng)基直接稀釋？還是需要通過PBS（含5%海藻糖）進(jìn)一步稀釋才行呢？
如果是直接做實驗，可以直接添加培養(yǎng)基進(jìn)行稀釋配置。 如果是需要長時間保存的話，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)胞因子加無菌水溶解后需要再次離心嗎？
加了無菌水后，如果沒有掛壁現(xiàn)象是不用離心的，如果您放置了一段時間，再次使用時是可以使用離心機(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.
