Description: Recombinant Human ARG1 Protein is produced by E. coli expression system and the target gene encoding Met1-lys322 is expressed with a 6His tag at the C-terminus. Form: Liquid in a 0.2 μM filtered solution of 20mM Tris-HCI, 150mM NaCl, 20% Glycerol, 1mM DTT, pH7.4. Gene Symbol: ARG1 Alternative Names: Arginase-1; Liver-type arginase; Type I arginaseEntrez Gene (Human): 383SwissProt (Human): P05089Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : MSAKSRTIGI IGAPFSKGQP RGGVEEGPTV LRKAGLLEKL KEQECDVKDY GDLPFADIPN DSPFQIVKNP RSVGKASEQL AGKVAEVKKN GRISLVLGGD HSLAIGSISG HARVHPDLGV IWVDAHTDIN TPLTTTSGNL HGQPVSFLLK ELKGKIPDVP GFSWVTPCIS AKDIVYIGLR DVDPGEHYIL KTLGIKYFSM TEVDRLGIGK VMEETLSYLL GRKKRPIHLS FDVDGLDPSF TPATGTPVVG GLTYREGLYI TEEIYKTGLL SGLDIMEVNP SLGKTPEEVT RTVNTAVAIT LACFGLAREG NHKPIDYLNP PKLEHHHHHH Directions 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 1X PBS. 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 : Store it at -20°C to -80°C for one year. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
