anti-Phospho-JKK1/SEK1/MKK4 Antibody

Phospho-SEK1/MKK4

MAP2K4, SERK1, MAPKKA, JNKK1, PRKMK4, MEK4

SAPK/Erk kinase (SEK1), also known as MKK4 or Jun kinase kinase (JNKK), activates the MAP kinase homologues SAPK and JNK in response to various cellular stresses and inflammatory cytokines. Activation of SEK1 occurs throμgh phosphorylation of serine and threonine residues at positions 257 and 261, respectively, by MEKK. Like MEK, SEK is a dual-specificity protein kinase that phosphorylates SAPK/JNK at a conserved T*PY* site in its activation loop. Phosphorylation by Akt at Ser80 inhibits SEK1 and suppresses the stress-activated signal transduction.

Rabbit

Polyclonal

Rabbit IgG

Human, mouse, rat

Synthetic peptide surrounding Ser80 of human SEK1/MKK4

0.5 mg/ml

Liquid

100 µg (0.5 mg/ml) peptide affinity purified rabbit polyclonal antibody in phosphate-buffered saline (PBS) containing 50% glycerol, 1% BSA, and 0.02% thimerosal.

Affinity purified

Western blot

Western blotting (1-4 µg/ml). However, the optimal concentrations should be determined individually. The antibody recognizes phosphorylated SEK1/MKK4/JKK1 of human, mouse, and rat origins.

Shelf time: 12 months in temp.: -20 deg.C

gel pack

The antibody solution should be gently mixed before use.

This antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.

If you buy Antibodies supplied by Biovision they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.
