Podoplanin, also termed GP38, is a 38 kD type I transmembrane sialoglycoprotein and a member of the podoplanin family. Mouse and human GP38 share 46% amino acid sequence homology. Alternative splicing transcripts, encoding different isoforms of GP38, have been identified. Structurally, GP38 has a 119 amino acid extracellular domain (ECD), a 21 amino acid transmembrane region, and a 10 amino acid cytoplasmic tail. This type I protein is heavily O-glycosylated and has a diverse distribution in human tissues, including glomerular epithelial cells, lung alveolar cells, lymphatic endothelial cells, and neural tissues. GP38 is also expressed by tumor cells such as testicular seminomas, squamous cell carcinomas, colorectal tumors, and brain tumors. Therefore, this protein is a target of antibody therapy in cancer treatment. GP38 induces platelet aggregation and tumor metastasis through its association with CLEC2. The binding of GP38 and CLEC2 is important for maintaining high endothelial cell venule integrity. Also, GP38 is necessary for lymphatic vessel formation, normal lung cell proliferation, and alveolus formation at birth. In addition, GP38 was shown to be a novel marker for immature hepatic progenitor cells in fetal livers. GP38 is upregulated in Th17 cells in the arthritic joints in SKG mice, suggesting that this protein could be a useful Th17 cell marker for diagnosing pathological conditions of autoimmune diseases, including rheumatoid arthritis.

• Learn more about our Recombinant Proteins. - How does the activity of your recombinant proteins compare to competitors?
-
We quality control each and every lot of recombinant protein. Not only do we check its bioactivity, but we also compare it against other commercially available recombinant proteins. We make sure each recombinant protein’s activity is at least as good as or better than the competition’s. In order to provide you with the best possible product, we ensure that our testing process is rigorous and thorough. If you’re curious and eager to make the switch to BioLegend recombinants, contact your sales representative today!
- What is the specific activity or ED50 of my recombinant protein?
-
The specific activity range of the protein is indicated on the product datasheets. Because the exact activity values on a per unit basis can largely fluctuate depending on a number of factors, including the nature of the assay, cell density, age of cells/passage number, culture media used, and end user technique, the specific activity is best defined as a range and we guarantee the specific activity of all our lots will be within the range indicated on the datasheet. Please note this only applies to recombinants labeled for use in bioassays. ELISA standard recombinant proteins are not recommended for bioassay usage as they are not tested for these applications.
- Have your recombinants been tested for stability?
-
Our testing shows that the recombinant proteins are able to withstand room temperature for a week without losing activity. In addition the recombinant proteins were also found to withstand four cycles of freeze and thaw without losing activity.
- Does specific activity of a recombinant protein vary between lots?
-
Specific activity will vary for each lot and for the type of experiment that is done to validate it, but all passed lots will have activity within the established ED50 range for the product and we guarantee that our products will have lot-to-lot consistency. Please conduct an experiment-specific validation to find the optimal ED50 for your system.
- How do you convert activity as an ED50 in ng/ml to a specific activity in Units/mg?
-
Use formula Specific activity (Units/mg) = 10^6/ ED50 (ng/mL)
