Description: Recombinant Human SPINK4 Protein is produced by Mammalian expression system and the target gene encoding Gly27-Cys86 is expressed with a 6His tag at the C-terminus. Form: Lyophilized from a 0.2 μM filtered solution of PBS, 1mM EDTA, 5% Mannitol, pH7.4. Gene Symbol: SPINK4 Alternative Names: Serine protease inhibitor Kazal-type 4; Peptide PEC-60 homologEntrez Gene (Human): 27290SwissProt (Human): O60575Purity : Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure : GKLPFSRMPI CEHMVESPTC SQMSNLVCGT DGLTYTNECQ LCLARIKTKQ DIQIMKDGKC VDHHHHHH 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 : 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.
