Target Info
Background
The cell surface glycoprotein TACD2 (or TROP2) is a protein that in humans is encoded by the TACSTD2 gene. It is a member of the tumor-associated calcium signal transducer family, closely related to epithelial cell adhesion molecules.
This protein plays a key role in intracellular calcium signaling, which is crucial for various cellular processes, including growth, division, and differentiation.
TACSTD2’s importance is particularly pronounced in the context of cancer biology; its overexpression has been observed in various carcinomas, including colorectal, gastric, and pancreatic cancers, making it a potential target for antibody drug conjugates and immunotherapy.
Mutation of TACD2 also are associated with gelatinous drop-like corneal dystrophy.

Material:
- PBS/EDTA solution
- 2% FBS/FCS in PBS (FACS Buffer)
- primary antibody (concentration is indicated under „Target expression“ tab)
Protocol:
Wash Protocol: Add FACS Buffer, resuspend cells gently, then centrifuge at 300×g for 5min.
- Prepare detection reagents in FACS buffer using the concentrations indicated under Materials.
- Aspirate medium from cells.
- Add PBS/EDTA solution to the cells and incubate at room temperature or 37°C for 5-10min, or until the cells detach.
- Wash cells 1×.
- Add primary antibody in FACS buffer, resuspend cells gently.
- Incubate at ambient temperature for 20-30min.
- Wash cells 2×.
- Resuspend in 100-200µl FACS Buffer.
- Analyse cells using a flow cytometer.
For a more detailed protocol, please see the BD Biosciences Quantibrite instructions.
Important: All instrument settings for fluorescence and compensation must be the same as the cellular assay settings.
- Reconstitute the BD Quantibrite beads using 0.5 mL of buffer, such as phosphate buffered saline (PBS) with sodium azide plus 0.5% bovine serum albumin (BSA), and vortex.
- Measure fluorescence of singlet beads using a flow cytometer and extract the geometric means of all four fluorescence peaks.
- Measure cells using the same instrument settings.
- Use the lot-specific values for the PE molecules per bead and linear regression to calculate the PE molecules per cell (approximation of target molecules per cell)
- For an even more meaningful result, contact the antibody provider for information on the number of fluorescent molecules per antibody.

Product FAQ
Yes, for selected targets, we provide cell lines that exhibit varying expression levels. Detailed information regarding the availability of different expression levels can be found in both the ‚Product Summary‘ and ‚Product Details‘ sections.
Cell lines with available expression level variations are denoted by an abbreviation following the catalog number. For instance, ‚INS-SF-1020-MH‘ denotes a cell line with medium-high expression levels, whereas ‚INS-SF-1020-L‘ indicates a cell line with low expression of the same target.
Should you require a specific expression level not readily available in our standard product range, we also offer custom cell line generation services utilizing our advanced Landing Pad technology.
For several targets, we already have ready-to-use cell lines available in both CHO and HEK293 backgrounds. Please refer to Related Products section, or have a look at our product catalog to see if your target and the desired cell line are listed.
For any other specific cell line background such as A549, MIA PaCa-2, or any other cell line, we currently do not offer pre-established cell lines. However, we are pleased to provide a custom cell line development service. Through this service, we can express your target in virtually any cell background utilizing random integration techniques, tailored to meet your research needs.
For the best performance of this cell line, we advise using our Medium and Coating Solutions specified in the product sheet. These have been specially optimized for these cells.
For our off-the-shelf stable recombinant cell line, we also disclose the Medium composition in the Product Sheet so you can make your ownMedium.
All our stable recombinant cell lines are provided as adherent cultures, if not indicated otherwise in the Product Sheet.
Some of our CHO cell lines can be easily adapted to suspension culture. If a particular cell line can be cultured in suspension is indicated in the product summary section at the top of the page under Cell Background, as well as in the Product Sheet, where you will also find detailed protocols for suspension culture.
Our stable recombinant cell lines are generated using our proprietary Landing Pad Technology, in which we use targeted integration at pre-validated genomic locations to express the target. You can find more details on our Landing Pad technologies under our Landing Pad Services.
After cell line generation, target expression levels were validated by Flow Cytometry using the reagents and protocols indicated in the section Product Details or in the Product Sheet.
This cell line is BSL 1 according to German legislation. However, persons working with such cell lines and their employers are required to familiarize themselves with the national regulations and safety precautions, as they may differ. Our provided biosafety classification does not provide any exemption from this responsibility.
