form :
Supplied as lyophilized form in 20mM Tris,150mM NaCl, pH8.0, containing 1mM EDTA, 1mM DTT,0.01% sarcosyl, 5% trehalose, and preservative.
storage stability :
Avoid repeated freeze/thaw cycles. Store at 2-8 degree C for one month. Aliquot and store at -80 degree C for 12 months. Stability Test: The thermal stability is described by the loss rate of the targetprotein. The loss rate was determined by accelerated thermal degradation test,that is, incubate the protein at 37 degree C for 48h, and no obvious degradation andprecipitation were observed. (Referring from China Biological Products Standard,which was calculated by the Arrhenius equation.) The loss of this protein is lessthan 5% within the expiration date under appropriate storage condition.
tested application :
Applications: SDS-PAGE; WB; ELISA; IP; CoIP; Purification; Amine Reactive Labeling. (May be suitable for use in other assays to be determined by the end user.)
other info1 :
Source: Prokaryotic expression. Residues: Met1~Gly258. Tags: N-terminal His-Tag. Tissue Specificity: Brain. Subcellular Location: Cytoplasm, cytosol. Golgi apparatus membrane; Cytoplasmic vesicle, secretory vesicle membrane; secretory vesicle. Peripheral membrane protein. Traits: Freeze-dried powder
other info2 :
Buffer formulation: 20mM Tris, 150mM NaCl, pH8.0, containing 1mM EDTA, 1mM DTT, 0.01% sarcosyl, 5%Trehalose and Proclin300. Predicted isoelectric point: 8.8. Predicted Molecular Mass: 36.9kDa. Accurate Molecular Mass: 27kDa as determined by SDS-PAGE reducing conditions. Usage: Reconstitute in 20mM Tris, 150mM NaCl (pH8.0) to a concentration of 0.1-1.0 mg/mL. Do not vortex. Phenomenon explanation: 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.

ncbi summary :
This gene encodes a protein with an arfaptin homology domain that is found both in the cytosol and as membrane-bound form on the Golgi complex and immature secretory granules. This protein is believed to be an autoantigen in insulin-dependent diabetes mellitus and primary Sjogren's syndrome. Several transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Feb 2013]
