[ PROPERTIES ]

Source: Prokaryotic expression. Host: E. coli

Residues: His1572~Lys1754

Tags: N-terminal His-Tag

Tissue Specificity: Liver, Lung, Kidney. Subcellular Location: Secreted, extracellular space, extracellular matrix. Purity: >98%

Traits: Freeze-dried powder

Buffer formulation: 100mM NaHCO3, 500mM NaCl, pH8.3, containing 1mM

EDTA, 1mM DTT, 0.01% sarcosyl, 5%Trehalose and Proclin300. Original Concentration: 200µg/mL

Applications: Positive Control; Immunogen; SDS-PAGE; WB. (May be suitable for use in other assays to be determined by the end user.)

Predicted isoelectric point: 9.5

Predicted Molecular Mass: 23.8kDa

Accurate Molecular Mass: 21kDa as determined by SDS-PAGE reducing conditions. [ USAGE ]

Reconstitute in 100mM NaHCO3, 500mM NaCl (pH8.3) to a concentration of

0.1-1.0 mg/mL. Do not vortex. [ STORAGE AND STABILITY ]

Storage: Avoid repeated freeze/thaw cycles. Store at 2-8

oC for one month. Aliquot and store at -80

oC for 12 months. Stability Test: The thermal stability is described by the loss rate. The loss rate

was determined by accelerated thermal degradation test, that is, incubate the

protein at 37

oC for 48h, and no obvious degradation and precipitation wereobserved. The loss rate is less than 5% within the expiration date under

appropriate storage condition.
