Background | Mitogen-activated protein kinases (MAPKs) are a widely conserved family of serine/threonine protein kinases involved in many cellular programs, such as cell proliferation, differentiation, motility, and death. The p44/42 MAPK (Erk1/2) signaling pathway can be activated in response to a diverse range of extracellular stimuli including mitogens, growth factors, and cytokines, and research investigators consider it an important target in the diagnosis and treatment of cancer. Upon stimulation, a sequential three-part protein kinase cascade is initiated, consisting of a MAP kinase kinase kinase (MAPKKK or MAP3K), a MAP kinase kinase (MAPKK or MAP2K), and a MAP kinase (MAPK). Multiple p44/42 MAP3Ks have been identified, including members of the Raf family, as well as Mos and Tpl2/COT. MEK1 and MEK2 are the primary MAPKKs in this pathway. MEK1 and MEK2 activate p44 and p42 through phosphorylation of activation loop residues Thr202/Tyr204 and Thr185/Tyr187, respectively. Several downstream targets of p44/42 have been identified, including p90RSK and the transcription factor Elk-1. p44/42 are negatively regulated by a family of dual-specificity (Thr/Tyr) MAPK phosphatases, known as DUSPs or MKPs, along with MEK inhibitors, such as U0126 and PD98059. |

保存條件:
p42 MAPK1 (Erk2) Rabbit Polyclonal Antibody (KO Validated) -20ºC保存,Western一抗稀釋液-20ºC或4ºC保存,一年有效。Western一抗稀釋液優先推薦4ºC保存,長期不使用可以考慮-20ºC保存,但凍融可能會導致出現輕微的渾濁和少量不溶物。
注意事項:
如果本抗體用于Western blot (WB)、免疫熒光(IF)、免疫細胞化學(ICC)等實驗,請注意回收使用過的稀釋抗體。回收的抗體通常至少可以重復使用5-10次。稀釋后的抗體,包括已經使用過的稀釋抗體,請4℃保存。
回收后重復使用的抗體,使用方法同新鮮稀釋的抗體。如果在重復使用過程中發現抗體出現輕微混濁現象,可以10,000g離心1-3分鐘,取上清用于后續檢測。如果回收的抗體出現明顯的絮狀物或長霉長菌等情況,則可以考慮廢棄該抗體。
提供的Western一抗稀釋液也可以用于免疫熒光(IF)、免疫組化(IHC)、免疫細胞化學(ICC)等適當用途。如果希望獲得最佳的檢測效果,請考慮使用上述檢測專用的一抗稀釋液。
