|Human Cell lysate that Human BPIFA2 / C20orf70 transfected / overexpressed for Western blot (WB) positive control. The whole cell lysate is provided in 1X Sample Buffer (1X modified RIPA buffer+1X SDS loading buffer).|
|A DNA sequence encoding the human C20orf70 (Q96DR5) (Met1-Ile249) was expressed with a polyhistidine tag at the C-terminus.|
|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.|
|Cell lysate was prepared by homogenization in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.|
|Modified RIPA Lysis Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF.|
|12.5% SDS-PAGE Stained with Coomassie Blue after protein purification.|
|Samples are stable for up to twelve months from date of receipt.|
|1. Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube. 2. Re-dissolve the pellet using 200μL pure water and boil for 2-5 min. 3. Store the lyophilized cell lysate at 4℃. After re-dissolution, recommend to aliquot it into smaller quantities and store at -80℃.|
|1 X Sample Buffer (1 X modified RIPA buffer+1 X SDS loading buffer).|
|Store at 4℃. After re-dissolution, aliquot and store at -80℃.|
|Western blot (WB): Use at an assay dependent dilution.|
Other Applications: Not tested.
Optimal dilutions/concentrations should be determined by the end user.
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.
