Datasheets
  • available in 100,000 units in 0.25 ml (sc-200312) and 20,000 units in 0.05 ml (sc-200312A) sizes
  • Bacteriophage λ, recombinant (E. coli)
  • Lambda Phosphatase can be used to release phosphate groups from phosphorylated serine, threonine and tyrosine residues in proteins; also active on phosphorylated histidine residues
  • 1 mL of 10X Reaction buffer and 1 mL of 10X MnCl2 included with each size
  • Lambda Phosphatase (Lambda PP) is a Mn2+-dependent protein phosphatase with activity towards phosphorylated serine, threonine and tyrosine residues. The enzyme is inhibited by vanadate ions and can be heat inactivated at 65° C for 1 hour in the presence of 50 mM EDTA
  • Purity: minimum 95% (SDS-PAGE) with no detectable protease, DNase, or RNase activity
  • supplied as a solution containing approximately 400,000 units of protein per ml in 50 mM Tris-HCl, pH 7.5, 0.1 mM EGTA, 0.01% BRIJ 35 and 50% glycerol
  • Unit Definition: One unit will hydrolyze 1 nmole of p-nitophenyl phosphate per minute at 30° C and pH 7.5

We need to fully inhibit lambda phosphatase activity, for downstream protein kinase assays (after dephosphorylating the kinase w/ lambda p'tase). Can you recommend which phosphatase inhibitor(s) would be most effective?

Can it be used for the treatment of protein lysates? I mean crude lysates cell lysates? if so, how would you recommend. thanks

Asked by: Sudheesh
Thank you for your question. Yes, the Lambda Phosphatase can be used for dephosphorylation of proteins in a crude cellular or tissue extract. Please refer to the procedure on the product data sheet on our website. If you have further questions, please contact us for Technical Support.

can we use this product for cloning in order to avoid self ligation ?

Asked by: rosa26
Thank you for your question. We have not tested this Lambda Phosphatase for this research application, so it is not known if it would be suitable for that use.

Dear sir, madam, Does Lambda PP also have reactivity towards phosphorylated carbohydrates (like CIP)? Or does it only dephosphorylate Tyr-Thr-Ser moieties? Kind regards, Jonas

Asked by: Jonas
Thank you for your question. We have not tested Lambda Phosphatase for use in this type of application, and we have no information whether it would work for dephosphorylating carbohydrates.

Rated 5 out of 5 by from Satisfying resultsUsed it for removing phosphate groups from a recombinant protein complex that was subsequently used as a substrate in a kinase assay. Worked like a charm.

Rated 5 out of 5 by from Works great- verstileI use this routinely to verify phospho- antibodies and to de-phosphorylate proteins for binding assays. I use Lambda Phospatase to de-phosphorylate proteins in a crude cell lysate, on a western blot itself, or on fixed cells on a cover slip.
