Uniprot/Accession: P46013 Amino Acid Sequence: MTDDKT TKIPCKSSPE LEDTATSSKR RPRTRAQKVE VKEELLAVGK LTQTSGETTH TDKEPVGEGK GTKAFKQPAK RKLDAEDVIG SRRQPRAPKE KAQPLEDLAS FQELSQTP Predicted Isoelectric Point: 6.7 Predicted Molecular Weight: 19.3kD Accurate Molecular Weight: 15/26kD as determined by SDS-PAGE reducing conditions Note: The possible reasons that the actual band size differs from the predicted are as follows: 1. Splice variants: Alternative splicing may create different sized proteins from the same gene 2. Relative charge: The composition of amino acids may affect the charge of the protein. 3. Post-translational modification: Phosphorylation, glycosylation, methylation etc. 4. Post-translation cleavage: Many proteins are synthesized as pro-proteins and then cleaved to give the active form. 5. Polymerization of the target protein: Dimerization, multimerization, etc. Subcellular Location: Nucleus, Chromosome Applications: Suitable for use in ELISA, Western Blot and SDS-PAGE. Other applications not tested. Recommended Dilutions: Optimal dilutions to be determined by the researcher. Storage and Stability: Lyophilized and reconstituted products are stable for 6 months after receipt at -70°C. Reconstitute with sterile 20mM Tris, 150mM sodium chloride, pH 8.0. Aliquot to avoid repeated freezing and thawing. Store at -70°C. 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. Note: Thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation by incubating the protein at 37°C for 48h, with no obvious degradation or precipitation observed. Protein loss is <5% within the expiration date under appropriate storage conditions.
