Description: Recombinant Human NP1 Protein is produced by mammalian expression system and the target gene encoding Gln23-Asn432 is expressed with a 6His tag at the C-terminus. Form: Lyophilized from a 0.2 μm filtered solution of PBS, 1mM EDTA, PH7.4. Gene Symbol: NPTX1 Alternative Names: Neuronal pentraxin-1; NP1; Neuronal pentraxin I; NP-IEntrez Gene (Human): 4884SwissProt (Human): Q15818Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : QDFGPTRFIC TSVPVDADMC AASVAAGGAE ELRSSVLQLR ETVLQQKETI LSQKETIREL TAKLGRCESQ STLDPGAGEA RAGGGRKQPG SGKNTMGDLS RTPAAETLSQ LGQTLQSLKT RLENLEQYSR LNSSSQTNSL KDLLQSKIDE LERQVLSRVN TLEEGKGGPR NDTEERVKIE TALTSLHQRI SELEKGQKDN RPGDKFQLTF PLRTNYMYAK VKKSLPEMYA FTVCMWLKSS ATPGVGTPFS YAVPGQANEL VLIEWGNNPM EILINDKVAK LPFVINDGKW HHICVTWTTR DGVWEAYQDG TQGGSGENLA PYHPIKPQGV LVLGQEQDTL GGGFDATQAF VGELAHFNIW DRKLTPGEVY NLATCSTKAL SGNVIAWAES HIEIYGGATK WTFEACRQIN HHHHHH 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 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.
