Recombinant Ribosome Binding Protein 1 (RRBP1) 

核糖體結(jié)合蛋白1(RRBP1)重組蛋白

[ PROPERTIES ]

Residues: Arg822~Val977

Tags: Two N-terminal Tags, His-tag and T7-tag

Accession: Q9P2E9

Host: E. coli

Subcellular Location: Endoplasmic reticulummembrane; Single-pass type III membrane protein.

Purity: >95%

Endotoxin Level: <1.0EU per 1μg

(determined by the LAL method).

Formulation: Supplied as lyophilized form in 20mM Tris,150mM NaCl, pH8.0, containing 1mM EDTA, 1mM DTT,0.01% sarcosyl, 5% trehalose, and preservative.

Predicted isoelectric point: 4.7

Predicted Molecular Mass: 21.1kDa

Accurate Molecular Mass: 30kDa as determined by SDS-PAGE reducingconditions.

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 cleavedto give the active form.

5. Polymerization of the target protein: Dimerization, multimerization etc.

[ USAGE ]

Reconstitute in sterile ddH₂O.

[ 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.
