Name :
Recombinant Human BPIFA2 Protein (hFc Tag)
Biological Activity :
Background :
C20orf70 belongs to the BPI/LBP/Plunc superfamily, Plunc family. PLUNC family is comprised by mucosal secretory proteins that are predicted to be structurally similar to lipid-binding and host-defense proteins including bactericidal/permeability-increasing protein and lipopolysaccharide-binding protein. C20orf70 can be detected in submandibular gland. C20orf70 gene contains 9 distinct gt-ag introns. Transcription produces 6 different mRNAs, 4 alternatively spliced variants and 2 unspliced forms. There are 2 probable alternative promotors, 3 non overlapping alternative last exons and 4 validated alternative polyadenylation sites. The mRNAs appear to differ by truncation of the 3′ end. 80 bp of this gene are antisense to spliced gene glopa, raising the possibility of regulated alternate expression. C20orf70 is expected to have molecular function (lipid binding) and to localize in extracellular region. It is a salivary protein of unknown function.

Protein Construction :
A DNA sequence encoding the human C20orf70 (Q96DR5) (Met1-Ile249) was expressed, fused with the Fc region of human IgG1 at the C-terminus.
Buffer Solution :
Lyophilized from sterile PBS, pH 7.4.Please contact us for any concerns or special requirements. Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hardcopy of datasheet.
Shipping :
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.
Redissolution :
A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
