Recombinant Larimichthys crocea Hepcidin (hamp) | CSB-EP010124LLH | Cusabio

Alternative Name(s): hamp; Hepcidin

Gene Names: hamp

Research Areas: Immunology

Organism: Larimichthys crocea (Large yellow croaker) (Pseudosciaena crocea)

AA Sequence: RCRFCCRCCPRMRGCGICCRF

Source: E.coli

Tag Info: Tag-Free

Expression Region: 65-85aa

Sequence Info: Full Length of Mature Protein

MW: 2.5 kDa

Purity: Greater than 90% as determined by SDS-PAGE.

Relevance: Seems to act as a signaling molecule involved in the maintenance of iron homeostasis. Seems to be required in conjunction with HFE to regulate both intestinal iron absorption and iron storage in macrophages Has very strong antibacterial activity against the marine Gram-negative bacteria V.alginolyticus (MIC=24 µM), V.fluvialis, V.harveyis (MIC=12 µM) and V.parahaemolyticus (MIC=6 µM). Has antibacterial activity against the Gram-negative bacteria A.hydrophila (MIC=6 µM), E.coli (MIC=24 µM), and E.coli BL21(DE3)plysS (MIC=6 µM), and the Gram-positive bacteria B.cereus (MIC=24 µM), B.subtilis (MIC=6 µM), C.glutamicum (MIC=3 µM), M.luteus (MIC=3 µM), M.lysodeikticus, S.aureus (MIC=6 µM) and S.epidermis (MIC=12 µM). Possesses antifungal activity against A.niger (MIC=24 µM), F.graminearum (MIC24 µM) and F.solani (MIC=24 µM), but lacks antifungal activity against the yeasts P.pastoris GS115 and C.albicans.

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.

Function: Seems to act as a signaling molecule involved in the maintenance of iron homeostasis. Seems to be required in conjunction with HFE to regulate both intestinal iron absorption and iron storage in macrophages (By similarity).

Involvement in disease:

Subcellular Location: Secreted

Protein Families: Hepcidin family

Tissue Specificity: Expressed in all tissues tested, with highest levels of expression in kidney and lowest levels in liver. Intra-peritoneal injection of lipopolysaccharide results in increased expression in heart, spleen and stomach, but not in kidney or liver.

Paythway:

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.

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.
