Blocking - Blocking peptide for Anti-PTP lambda antibody (ab13223)
- First try to dissolve a small amount of peptide in either water or buffer. The more charged residues on a peptide, the more soluble it is in aqueous solutions. - If the peptide doesn’t dissolve try an organic solvent e.g. DMSO, then dilute using water or buffer. - Consider that any solvent used must be compatible with your assay. If a peptide does not dissolve and you need to recover it, lyophilise to remove the solvent. - Gentle warming and sonication can effectively aid peptide solubilisation. If the solution is cloudy or has gelled the peptide may be in suspension rather than solubilised. - Peptides containing cysteine are easily oxidised, so should be prepared in solution just prior to use.

PTP lambda is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle and oncogenic transformation. PTP lambda is a large protein that possesses a C-terminus PTP domain and multiple noncatalytic domains which include a domain with similarity to band 4.1 superfamily of cytoskeletal-associated proteins, a region consisting of five PDZ domains and a leucine zipper motif. Four alternatively spliced transcript variants, which encode distinct proteins, have been reported.
PTP lambda is up-regulated upon cell contact and is found in high levels in brain, pancreas, and skeletal muscle; less in colon, kidney, liver, stomach and uterus. It is not expressed in placenta and spleen.
