Background

The TCN2/Transcobalamin-2 protein takes on the pivotal role of being the primary vitamin B12-binding and transport protein, facilitating the delivery of cobalamin to cells. Through its intricate interactions, TCN2 engages with CD320, specifically binding to LDL-receptor class A domains. This molecular partnership suggests a coordinated mechanism for the targeted delivery of vitamin B12 to cells, emphasizing the protein's crucial role in the efficient transport and uptake of this essential nutrient.

Biological Activity

Measured by its binding ability in a functional ELISA. Immobilized CD320 at 25 ng/mL (100 μL/well) can bind Biotinylated TCN2. The ED50 for this effect is 11.18 ng/mL, corresponding to a specific activity is 8.94×10^4 Unit/mg.

Molecular Weight

Approximately 42.4 kDa

Purity
  • Greater than 95% as determined by reducing SDS-PAGE.
Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.2 μm filtered solution of 20 mM HAc-NaAc, 150 mM NaCl, pH 4.0 or 20 mM PB, 150 mM NaCl, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
