Recombinant Cardiac Troponin I (cTnI)
心肌肌钙蛋白I(cTnI)重组蛋白
[ PROPERTIES ]
Source: Prokaryotic expression
Host: E.coli
Residues: Met1~Gly203
Tags: N-terminal His -Tag
Subcellular Location: Secreted
Purity: > 97%
Traits: Freeze-dried powder
Buffer formulation: PBS, pH7.4, containing 0.01% SKL, 5% Trehalose .
Original Concentration: 300µg/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: 9.7
Predicted Molecular Mass: 24.4kDa
Accurate Molecular Mass: 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 10mM 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 2-8ºC for one month.
Aliquot and store at -80ºC 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°C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.
