| 目标基因介绍 | Non-receptor tyrosine-protein kinase that plays a role in many biological processes including regulation of cell growth and survival, cell adhesion, integrin-mediated signaling, cytoskeletal remodeling, cell motility, immune response and axon guidance. Inactive FYN is phosphorylated on its C-terminal tail within the catalytic domain. Following activation by PKA, the protein subsequently associates with PTK2/FAK1, allowing PTK2/FAK1 phosphorylation, activation and targeting to focal adhesions. Involved in the regulation of cell adhesion and motility through phosphorylation of CTNNB1 (beta-catenin) and CTNND1 (delta-catenin). Regulates cytoskeletal remodeling by phosphorylating several proteins including the actin regulator WAS and the microtubule-associated proteins MAP2 and MAPT. Promotes cell survival by phosphorylating AGAP2/PIKE-A and preventing its apoptotic cleavage. Participates in signal transduction pathways that regulate the integrity of the glomerular slit diaphragm (an essential part of the glomerular filter of the kidney) by phosphorylating several slit diaphragm components including NPHS1, KIRREL1 and TRPC6. Plays a role in neural processes by phosphorylating DPYSL2, a multifunctional adapter protein within the central nervous system, ARHGAP32, a regulator for Rho family GTPases implicated in various neural functions, and SNCA, a small pre-synaptic protein. Participates in the downstream signaling pathways that lead to T-cell differentiation and proliferation following T-cell receptor (TCR) stimulation. Phosphorylates PTK2B/PYK2 in response to T-cell receptor activation. Also participates in negative feedback regulation of TCR signaling through phosphorylation of PAG1, thereby promoting interaction between PAG1 and CSK and recruitment of CSK to lipid rafts. CSK maintains LCK and FYN in an inactive form. Promotes CD28-induced phosphorylation of VAV1. In mast cells, phosphorylates CLNK after activation of immunoglobulin epsilon receptor signaling (By similarity). | ||

| 复苏 | 1）在37℃水浴中预热完全培养基。 2）将冻存管在 37℃水浴中解冻1-2分钟。 3）将冻存管转移到生物安全柜中，并用70%乙醇擦拭表面。 4）拧开冻存管管盖，将细胞悬液轻轻转移到含有9mL完全培养基的无菌离心管中。 5）在室温下以125g离心5-7分钟，弃上清。 6）用5mL的完整培养基重悬细胞沉淀，将细胞悬液转移到T25培养瓶中。 7）将细胞转移到37℃，5% CO2的培养箱中培养。 8）参考传代比例：1/2到1/3传代，2-5天长满。 | ||
| 传代 | 1）待培养瓶中细胞汇合度至80%-90%以上，可进行细胞传代。 2）将培养基、PBS、胰酶（0.25%Trypsin_EDTA Gibco 25200-056）等从4℃冰箱中拿出，置于37℃水浴中温度接近37℃时取出并在瓶子表面喷洒75%酒精后置于生物安全柜中。 3）从培养箱中取出待传代的培养瓶，瓶身喷洒75%酒精后置于生物安全柜中。 4）为避免冲散细胞，沿培养瓶上壁PBS润洗细胞，清洗细胞后弃去，T25加2mL。 5）加入对应体积的胰酶（T75加1.5mL，T25加0.5mL），并轻轻晃动瓶身使胰酶平铺满细胞底部。可根据实际情况适当增加或减少用量。约1-2min后大部分细胞脱落时，加入对应体积的完全培养基终止消化，并用5mL移液管轻轻吹打至细胞全部脱落。 6）将细胞悬液转移至15mL离心管，悬液300g离心5min，弃上清。 7）移取5mL完全培养基重悬细胞，按需求调整接种比例，并补充培养瓶中完全培养基，T75加至13-15mL，T25加至5mL，加1%双抗。 8）盖上瓶盖拧紧后轻轻晃动瓶身，使细胞混合均匀后置于37℃，5% CO4培养箱中。 | ||
| 细胞冻存 | 1）准备冻存液，并提前预冷。 2）确保待冻存的细胞满足冻存要求，用显微镜检查以下状态：健康的外观及形态特征、所处生长周期（对数晚期）、无污染或衰退迹象。 3）对细胞进行消化及离心处理（具体步骤参考传代培养流程） 4）按照每管1mL的量添加冻存液重悬细胞，吹打均匀后分装至冻存管。 5）将细胞放在程序降温盒中，在-80℃冰箱中冷冻。 6）后续将细胞转移到液氮罐中，以便长期储存。 | ||
