adenylyl cyclase   Coleonol   Colforsin   cyclic AMP   gene transcription   ion transport   protein phosphorylation  

Applications Dilution Species-Reactivity Sensitivity MW (kDa) Isotype

Species cross-reactivity is determined by western blot.

Applications Key:

Western Blotting

Western Blotting

Western blot analysis of extracts from SH-SY5Y cells, forskolin-treated (30 µM for 20 min.) or untreated, using Phospho-CREB (Ser133) Antibody #9191 (upper) or CREB Antibody #9192 (lower).对SH-SY5Y细胞抽提液,30 uM forskolin处理20分钟或未处理,使用Phospho-CREB (Ser133)抗体#9191(上图)或CREB抗体#9192(下图)进行Western blot分析。

Directions for Use

Forskolin is soluble in DMSO and methanol. DMSO solutions can be stored at -20ºC in the dark for at least six months.



Forskolin, a naturally occurring diterpene from the Indian plant, Coleus forskohlii, activates adenylate cyclase, and thus increases the intracellular cAMP concentration (1). The second messenger cAMP activates cAMP-dependent protein kinase (PKA or cAPK) and controls many cellular mechanisms such as gene transcription, ion transport and protein phosphorylation (2).


Purity is greater than 99% as determined by HPLC and TLC.
