N-Cadherin (NCAD), also known as Cadherin-2 (CDH2), is a type I membrane protein that preferentially interacts in a homophilic manner. It is a member of the Cadherin super family, a family of calcium dependent cell adhesion molecules. N-Cadherin is primarily expressed in mesenchymal tissues such as neural tissue, retina, endothelial cells, fibroblasts, osteoblasts, mesothelium, myocytes, limb cartilage, oocytes, spermatids, and Sertoli cells. Human N-Cadherin is a 906 amino acid protein with a 25 amino acid signal peptide, a 134 amino acid N-terminal propeptide, a 565 amino acid extracellular domain, a 21 amino acid transmembrane domain, and a 161 amino acid cytoplasmic domain. N-Cadherin shares 98% amino acid sequence identity with both mouse and rat N-Cadherin within the extracellular domain. The N-Cadherin ectodomain can be cleaved by MMP24 which leads to the generation of a soluble 90 kD N-terminal soluble fragment and a 45 kD membrane-bound carboxy-terminal fragment 1. The Carboxy-terminal fragment is further cleaved by gamma-secretase into a 35 kD fragment. MMP24 mediated N-Cadherin cleavage in neural stem cells affects N-Cadherin mediated anchorage of neural stem cells to ependymocytes in the adult, leading to the modulation of neural stem cell quiescence. N-Cadherin is not only involved in cell-cell adhesion, but also in cell differentiation, embryogenesis, migration, invasion and signal transduction. Fibroblast growth factor receptor interaction with N-Cadherin has been implicated in contact-dependent survival of ovarian granulosa cells in a FGFR dependent manner. N-cadherin/FGFR also have a pivotal role in promoting metastasis through differential regulation of ERK and AKT. Due to N-Cadherin’s influence on cell migration and invasion, an upregulation of N-Cadherin has been shown to be common amongst aggressive cancer types. N-Cadherin promotes the survival of cancer cells by accelerating migration and invasion of cancer cells.Product Details
- Antibody Type
- Mouse N-Cadherin, amino acids Met1-Ala724 (Accession # NM_007664.4) with a C-terminal human IgG Fc (Pro100-Lys330) was expressed in 293E cells.
- Molecular Mass
- The recombinant protein consists of 804 amino acid mature form and 938 amino acid pro-protein with predicted molecular mass of approximately 88.6 kD and 103.9 kD respectively. The DTT-reduced proteins migrate at approximately 110 kD and 130 kD, and non-reduced proteins migrate at approximately 240-270 kD by SDS-PAGE. The predicted N-terminal amino acid is Asp and Ser.
- 0.22 μm filtered protein solution is in PBS, pH 7.2
- Endotoxin Level
- Less than 0.1 EU per μg protein as determined by the LAL method.
- 10-25 µg sizes are bottled at 200 µg/mL. 100 µg and larger sizes are lot-specific and bottled at the concentration indicated on the vial. (Please contact technical support for concentration, or use our Lookup tool if you have a lot number.)
- Storage & Handling
- Unopened vial can be stored between 2°C and 8°C for one month, at -20°C for six months, or at -70°C for one year. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C to -70°C. Stock solutions can also be prepared at 50 - 100 µg/mL in sterile buffer (PBS, HPBS, DPBS, or EBSS) containing carrier protein such as 0.2-1% BSA or HSA and stored in working aliquots at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
- ED50 = 0.2 - 0.8 μg/mL as measured by the ability of immobilized protein to support the adhesion of U-118-MG cells. Calcein-AM (Cat. No. 425201) was used to measure the number of adherent cells.
- Application Notes
BioLegend carrier-free recombinant proteins provided in liquid format are shipped on blue ice. Our comparison testing data indicates that when handled and stored as recommended, the liquid format has equal or better stability and shelf-life compared to commercially available lyophilized proteins after reconstitution. Our liquid proteins are validated in-house to maintain activity after shipping on blue ice and are backed by our 100% satisfaction guarantee. If you have any concerns, contact us at firstname.lastname@example.org.
Primarily expressed in mesenchymal tissue such as: neural tissue, retina, endothelial cells, fibroblasts, osteoblasts, mesothelium, myocytes, limb cartilage, oocytes, spermatids, and Sertoli cells.

- 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.
- 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.
- How do you convert activity as an ED50 in ng/ml to a specific activity in Units/mg?
- Use formula Specific activity (Units/mg) = 10e6/ ED50 (ng/mL)
- 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.
