Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 20-516aa. Protein Length: Partial. Tag Info: N-terminal 6xHis-tagged. Target Protein Sequence: GHWGAWMPSS ISAFEGTCVS IPCRFDFPDE LRPAVVHGVW YFNSPYPKNY PPVVFKSRTQ VVHESFQGRS RLLGDLGLRN CTLLLSNVSP ELGGKYYFRG DLGGYNQYTF SEHSVLDIVN TPNIVVPPEV VAGTEVEVSC MVPDNCPELR PELSWLGHEG LGEPAVLGRL REDEGTWVQV SLLHFVPTRE ANGHRLGCQA SFPNTTLQFE GYASMDVKYP PVIVEMNSSV EAIEGSHVSL LCGADSNPPP LLTWMRDGTV LREAVAESLL LELEEVTPAE DGVYACLAEN AYGQDNRTVG LSVMYAPWKP TVNGTMVAVE GETVSILCST QSNPDPILTI FKEKQILSTV IYESELQLEL PAVSPEDDGE YWCVAENQYG QRATAFNLSV EFAPVLLLES HCAAARDTVQ CLCVVKSNPE PSVAFELPSR NVTVNESERE FVYSERSGLV LTSILTLRGQ AQAPPRVICT ARNLYGAKSL ELPFQGAHRL MWAKIGP. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. 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 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. 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 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Adhesion molecule that mediates interactions between myelinating cells and neurons by binding to neuronal sialic acid-containing gangliosides and to the glycoproteins RTN4R and RTN4RL2. Not required for initial myelination, but seems to play a role in the maintenance of normal axon myelination. Protects motoneurons against apoptosis, also after injury, protection against apoptosis is probably mediated via interaction with neuronal RTN4R and RTN4RL2. Required to prevent degeneration of myelinated axons in adults, this probably depends on binding to gangliosides on the axon cell membrane. Negative regulator of neurite outgrowth, in dorsal root ganglion neurons the inhibition is mediated primarily via binding to neuronal RTN4R or RTN4RL2 and to a lesser degree via binding to neuronal gangliosides. In cerebellar granule cells the inhibition is mediated primarily via binding to neuronal gangliosides. In sensory neurons, inhibition of neurite extension depends only partially on RTN4R, RTN4RL2 and gangliosides. Inhibits axon longitudinal growth. Inhibits axon outgrowth by binding to RTN4R. Preferentially binds to alpha-2,3-linked sialic acid. Binds ganglioside Gt1b. Reference: n/a. Function: nan
