Specificity and cross-reactivity

Detects endogenous levels of human SEK1/ MKK4 protein only when phosphorylated at threonine 261. Does not crossreact with the corresponding phosphorylated residues of MEK1, MEK2 or MKK3. Species Crossreactivity: Mouse and rat.

Purification method

Affinity Purified by Protein A affinity chromatography.


Supplied as liquid in 10mM HEPES, pH 7.5, 150mM sodium chloride, 0.1mg/ml BSA, 50% glycerol. No preservative added.



Storage and shipping

Store at 4 degrees Celsius for short term storage.. For long-term storage, For optimal long term storage, productone should be kept at -20 degrees Celsius. Aliquots are stable for at least 12 months productone should be stored at -20 degrees Celsius.. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Tested for:

ELISA (EL/EIA), Western Blot (WB)


productone is a polyclonal antibody of high purity and binding affinity for the antigen that it is risen against. Properly used, this antibody will ensure excellent and reproducible results with guaranteed success for the applications that it is tested in. Polyclonal antibodies have series of advantages - larger batches can be supplied at a time, they are inexpensive to manufacture and respectively to buy, the time needed for production is considerably shorter. Polyclonal antibodies generally are more stable and retain their reactivity under unfavorable conditions. To obtain more detailed information on productone, please, refer to the full product datasheet.


In order to retain the quality and the affinity of productone unchanged, please, avoid cycles of freezing and thawing. For antibodies that are in liquid form or reconstituted lyophilized antibodies small amounts could become entrapped on the seal or the walls of the tube. Prior to use briefly centrifuge the vial to gather all the solution on the bottom.


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