Description：Recombinant Rat GM-CSF Protein is produced by mammalian expression system and the target gene encoding Ala18-Lys144 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μm filtered solution of PBS pH7.4.Gene Symbol：CSF2Alternative Names：GMCSF; Granulocyte-macrophage colony-stimulating factor; GM-CSF; Colony-stimulating factor; CSF; Molgramostin; Sargramostim Entrez Gene (Rat)： 116630; SwissProt (Rat)： P48750; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：APTRSPNPVT RPWKHVDAIK EALSLLNDMR ALENEKNEDV DIISNEFSIQ RPTCVQTRLK LYKQGLRGNL TKLNGALTMI ASHYQTNCPP TPETDCEIEV TTFEDFIKNL KGFLFDIPFD CWKPVQKVDH HHHHHDirections for Use：Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Quality Control：Endotoxin: Less than 0.1 ng/µg (1 IEU/µg) as determined by LAL test.Storage/Stability：Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.
