Testing in progress
A DNA sequence encoding the human C20orf70 (Q96DR5) (Met1-Ile249) was expressed with a polyhistidine tag at the C-terminus.
Predicted N Terminal
The recombinant human C20orf70 consists of 242 amino acids and predicts a molecular mass of 26.5 KDa. It migrates as an approximately 35 KDa band in SDS-PAGE under reducing conditions.
Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us
for any concerns or special requirements.Please refer to the specific buffer information in the hard copy of CoA.
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.
Stability & Storage
Samples are stable for up to twelve months from date of receipt at -70℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

BPIFA2 Background Information
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.
