組織金屬蛋白酶抑制因子3(TIMP3)重組蛋白

Recombinant Tissue Inhibitors Of Metalloproteinase 3 (TIMP3)

SFD; TIMP Metallopeptidase Inhibitor 3; Metallopeptidase Inhibitor 3; Sorsby Fundus Dystrophy; Pseudoinflammatory

[ PROPERTIES ]

Source: Prokaryotic expression. Host: E. coli

Residues: Gly20~Pro211

Tags: N-terminal His-Tag

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

Traits: Freeze-dried powder

Buffer formulation: PBS, pH7.4, containing 1mM DTT, 5% trehalose, 0.01%

sarcosyl 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: 9.0

Predicted Molecular Mass: 23.3kDa

Accurate Molecular Mass: 22&28kDa as determined by SDS-PAGE reducing

conditions. 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.

[ USAGE ]

Reconstitute in PBS (pH7.4) 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 ratewas determined by accelerated thermal degradation test, that is, incubate the

protein at 37oC for 48h, and no obvious degradation and precipitation wereobserved. The loss rate is less than 5% within the expiration date under

appropriate storage condition.
