N-terminal 6xHis-tagged

Target Protein AA Sequence:

FWGALAKGALKLIPSLFSSFSKKD

Expression Region:

1-24aa

Subcellular Location:

Secreted, Target cell membrane

Tissue Specificity:

Expressed by the venom gland.

Protein Length:

Full Length

Pathway:

Mol. Weight:

4.6 kDa

Purity:

Greater than 90% as determined by SDS-PAGE.

Form:

Liquid or Lyophilized powder

Buffer:

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

Research Areas:

Others

Function:

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.

Reconstitution:

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
