XG, Recombinant, Human, aa22-142, His-Tag (Glycoprotein Xg Isoform 1 Precursor, PBDX)

XG is the XG blood group antigen, and is at the pseudoautosomal boundary on the short (p) arm of chromosome X. The three 5' exons reside in the pseudoautosomal region and the remaining exons within the X- specific end. A truncated copy of this gene is found on the Y chromosome at the pseudoautosomal boundary. It is transcribed, but not expected to make a Y-chromosome specific gene product. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. \n\nSource: \nRecombinant protein corresponding to human XG, fused to His-tag at N-terminal expressed in E.coli.\n\nMolecular Weight: \n~15.5kD (144aa) (MALDI-TOF)\n\nAA Sequence:\nMGSSHHHHHH SSGLVPRGSH MGSQRDFDLA DALDDPEPTK KPNSDIYPKP KPPYYPQPEN PDSGGNIYPR PKPRPQPQPG NSGNSGGYFN DVDRDDGRYP PRPRPRPPAG GGGGGYSSYG NSDNTHGGDH HSTYGNPEGN MVAK\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only.
