TMED4 Protein, Human, Recombinant (His Tag)

• Background:

  TMED4, also known as ERS25, belongs to the EMP24/GP25L family. TMED4 may play a role in the regulation of heat-shock response and apoptosis. It is involved in vesicular protein trafficking, mainly in the early secretory pathway. TMED4 may also play a role in the biosynthesis of secreted cargo including processing. It functions in the regulation of heat-shock response and apoptosis. TMED4 also is involved in endoplasmic reticulum stress response.

• Synonyms:

  ERS25 Protein, Human; GMP25iso Protein, Human; HNLF Protein, Human; p24alpha3 Protein, Human

  Transmembrane emp24 protein transport domain containing 4

• UniProt:

  Q7Z7H5-1

• Expression System:

  HEK293 Cells

• Tag:

  C-His

• Endotoxin:

  < 1.0 EU per μg of the protein as determined by the LAL method.

• Purity:

  > 85 % as determined by SDS-PAGE.

• Activity:

  At Leading Biology, the biological activity of a recombinant protein is routinely measured using a bioassay, e.g. chemotaxis or cell proliferation assay, enzyme assay, or a functional ELISA. When a recombinant protein is an enzyme, specific activity is derived from an enzymatic assay. Each enzyme is tested for potency by cleavage of a substrate. We are in the process of updating the biological activity data. If you have any questions regarding this update, please feel free to contact our technical support team.

• Form:

  Lyophilized

• Buffer:

  Lyophilized from sterile PBS, 10% Glycerol, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

• Molecular Weight:

  The recombinant human TMED4 consists of 176 amino acids and predicts a molecular mass of 20.7 KDa. It migrates as an approximately 23 KDa band in SDS-PAGE under reducing conditions.

• Storage Conditions:

  In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
