Source: Yeast

Tag Info: N-terminal 6xHis-tagged

Expression Region: 24-433aa

Sequence Info: Full Length of Mature Protein

MW: 47.6 kDa

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

Relevance: Binds vitamin B12 with ftomolar affinity and protects it from the acidic environment of the stomach.

Reference: Structure of the cDNA encoding transcobalamin I, a neutrophil granule protein.Johnston J., Bollekens J., Allen R.H., Berliner N.J. Biol. Chem. 264:15754-15757(1989)

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: Binds vitamin B12 with femtomolar affinity and protects it from the acidic environment of the stomach.

Involvement in disease:

Subcellular Location: Secreted

Protein Families: Eukaryotic cobalamin transport proteins family

Tissue Specificity: Produced by the salivary glands of the oral cavity, in response to ingestion of food. Major constituent of secondary granules in neutrophils.

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.
