Organism: Pandinus imperator (Emperor scorpion)
AA Sequence: FWGALAKGALKLIPSLFSSFSKKD
Expression Region: 1-24aa
Sequence Info: Full Length
Source: Yeast
Tag Info: N-terminal 6xHis-tagged
MW: 4.6 kDa
Alternative Name(s): Non-disulfide-bridged peptide 3.1 Short name: NDBP-3.1 Non-disulfide-bridged peptide 4.1 Short name: NDBP-4.1
Relevance: Disrupts cell membranes through formation of pores. Has strong antimicrobial activity against Gram-positive bacteria B.subtilis, S.epidermidis, E.faecalis and S.aureus. Is less active against Gram-negative bacteria P.aeruginosa and E.coli. Also increases efficacy of antibiotics (ampicillin, chloramphenicol, streptomycin, kanamycin, novobiocin) when tested against E.coli, probably by facilitating their incorporation into the bacteria. Possesses antifungal activity against C.albicans and hemolytic activity against human, sheep and pig erythrocytes.

Purity: Greater than 90% as determined by SDS-PAGE.
Storage Buffer: Tris-based buffer，50% glycerol
Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.
Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
