Recombinant Human ERBB2 Protein, His/GST-tagged, Alexa Fluor 555 conjugated

Specification :
| Source : Insect cells | Species : Human | Tag : His/GST | Form : Lyophilized | Bio-activity : No Kinase Activity | Molecular Mass : The recombinant human ErbB2 (676-1255)/GST chimera consists of 817 amino acids and predictes a molecular mass of 92 kDa. It migrates as an approximately 100 kDa band in SDS-PAGE under reducing conditions. | Protein length : 817 | N-terminal Sequence Analysis : Gln 26 | Endotoxin : | Purity : > 75 % as determined by SDS-PAGE | Characteristic : Disulfide-linked homodimerLabeled with Alexa Fluor 555 via aminesWith an excitation and emission maximum of 555/565 nm, Alexa Fluor 555 can be efficiently excited using a 543 nm He-Ne laser line and detected under standard TRITC/Cy3 filters. | Stability : Samples are stable for up to 12 months from date of receipt at -70 centigrade. | Storage : Store it under sterile conditions at -20 to-70 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. | Storage Buffer : Lyophilized from sterile 20 mM Tris, 500 mM NaCl, 2 mM GSH, 10% gly, pH 8.0, 5%-8% trehalose and mannitol. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 μg/μL. Centrifuge the vial at 4 centigrade before opening to recover the entire contents.
