Source

Recombinant Human BTN3A3 Protein (rh BTN3A3) Gln 30 - Trp 248 (Accession # AAH15815) was produced in human 293 cells (HEK293) at ACROBiosystems.

Molecular Characterization

rh BTN3A3 is fused with a polyhistidine tag at the C-terminus, and has a calculated MW of 25.5 kDa. The predicted N-terminus is Gln 30. DTT-reduced Protein migrates as 28 kDa in SDS-PAGE due to glycosylation.

Endotoxin

Less than 1.0 EU per μg of the rh BTN3A3 by the LAL method.

Purity

>95% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH 7.4. Normally Mannitol or Trehalose are added as protectants before lyophilization.

Contact us for customized product form or formulation.

Reconstitution

See Certificate of Analysis for reconstitution instructions and specific concentrations.

Storage

Avoid repeated freeze-thaw cycles.

No activity loss was observed after storage at:
In lyophilized state for 1 year (4oC); After reconstitution under sterile conditions for 3 months (-70oC).

 

SDS-PAGE


Recombinant Human BTN3A3 Protein
The purity of rh BTN3A3 was determined by DTT-reduced (+) SDS-PAGE and staining overnight with Coomassie Blue.
 
 

Background

Butyrophilin subfamily 3 member A3 (BTN3A3),a member of the immunoglobulin superfamily and BTN/MOG family, is also known as BTF3, which contains one B30.2/SPRY domain and two Ig-like V-type (immunoglobulin-like) domains. BTN3A3 is detected in peripheral blood mononuclear cells ,T-cells ,spleen and lymphocytes. BTN3A3 also plays a role in T-cell responses in the adaptive immune response. Stimulation of human butyrophilin 3(BTN3) molecules results in negative regulation of cellular immunity.
