[ PROPERTIES ]
Residues: Ala141~His286
Tags: Two N-terminal Tags, His-tag and S-tag
Accession: Q99519
Host: E. coli
Subcellular Location: Lysosome membrane;
Peripheral membrane protein; Lumenal side.
Lysosome lumen. Cell membrane. Cytoplasmic
vesicle.
Purity: >90%
Endotoxin Level: <1.0EU per 1μg
(determined by the LAL method).
Formulation: Supplied as lyophilized form in 10mM
PBS, pH7.4, containing 1mM DTT, 5% trehalose,
0.01% sarcosyl and preservative.
Predicted isoelectric point: 5.5
Predicted Molecular Mass: 21.6kDa
Accurate Molecular Mass: 26kDa as determined by SDS-PAGE reducing conditions.
Applications: SDS-PAGE; WB; ELISA; IP.
(May be suitable for use in other assays to be determined by the end user.)
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 affects 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.
神经氨酸酶(NEU)重组蛋白[ USAGE ]
Reconstitute in sterile ddH2O.
[ STORAGE AND STABILITY ]
Storage: Avoid repeated freeze/thaw cycles.
Store at 2-8
oC for one month.
Aliquot and store at -80oC for 12 months.
Stability Test: The thermal stability is described by the loss rate of the target
protein. The loss rate was determined by accelerated thermal degradation test,
that is, incubate the protein at 37oC for 48h, and no obvious degradation and
precipitation were observed. (Referring from China Biological Products Standard,
which was calculated by the Arrhenius equation.) The loss of this protein is less
than 5% within the expiration date under appropriate storage condition.
