特异性ab76583 only detects Stathmin 1 phosphorylated on Serine 62.
The antibody immunogen shares 86% homology with Stathmin-2, therefore it is possible that the antibody will cross-react with Stathmin-2 when phosphorylated at serine 97. This has not been assessed experimentally.
HeLa cell lysates treated with Calyculin A; human brain tissue.

存放说明Shipped at 4°C. Upon delivery aliquot and store at -20°C. Avoid repeated freeze / thaw cycles.
功能Involved in the regulation of the microtubule (MT) filament system by destabilizing microtubules. Prevents assembly and promotes disassembly of microtubules. Phosphorylation at Ser-16 may be required for axon formation during neurogenesis. Involved in the control of the learned and innate fear.
组织特异性Ubiquitous. Expression is strongest in fetal and adult brain, spinal cord, and cerebellum, followed by thymus, bone marrow, testis, and fetal liver. Expression is intermediate in colon, ovary, placenta, uterus, and trachea, and is readily detected at substantially lower levels in all other tissues examined. Lowest expression is found in adult liver. Present in much greater abundance in cells from patients with acute leukemia of different subtypes than in normal peripheral blood lymphocytes, non-leukemic proliferating lymphoid cells, bone marrow cells, or cells from patients with chronic lymphoid or myeloid leukemia.
序列相似性Belongs to the stathmin family. Contains 1 SLD (stathmin-like) domain.
翻译后修饰Many different phosphorylated forms are observed depending on specific combinations among the sites which can be phosphorylated. MAPK is responsible for the phosphorylation of stathmin in response to NGF. Phosphorylation at Ser-16 seems to be required for neuron polarization (By similarity). Phosphorylation at Ser-63 reduces tubulin binding 10-fold and suppresses the MT polymerization inhibition activity.

Dot Blot - Anti-Stathmin 1 (phospho S63) antibody [EPR1574] (ab76583)
Dot blot analysis of Stathmin 1 (phospho S63) phospho peptide (Lane 1) and Stathmin 1 non-phospho peptide (Lane 2) labeling Stathmin 1 (phospho S63) with ab76583 at a dilution of 1/1000. ab97051 (Peroxidase conjugated goat anti-rabbit IgG) (H+L) at 1/100 000 was used as the secondary antibody.
Blocking and diluting buffer: 5% NFDM/TBST.
Exposure time: 3 minutes.

Alkaline phosphatase treatment removes S63 phosphorylation.
Samples treated with phosphatase were run alongside the normal lysate, and the phosph-S63 signal is not detected after phosphatase treatment, thus suggesting the signal is very specific to the phosphorylated S63. Whole cell lysate prepared from a human colon cancer cell line was loaded at 20µg.ab76583 used at a 1/1000 dilution. Secondary used was an HRP conjugated goat anti-rabbit polyclonal used at a 1/10000 dilution.
