Invitrogen™ Cytokeratin 7 Monoclonal Antibody (LP5K), eFluor™ 615, eBioscience™
Description
This LP5K monoclonal antibody reacts with human cytokeratin 7 (K7), a 54-kDa type II (or basic) keratin expressed either alone or paired with cytokeratin 19 in simple epithelia, mesothelium, urothelium, and pseudostratified epithelium. Expression of cytokeratin 7 in the gastric foveolar, intestinal, and stratified squamous epithelia is extremely low or undetectable. Cytokeratins form the intracellular cytoskeletal network that maintains the integrity and stability of cells and tissues. In addition, most carcinomas express cytokeratin 7. The coordinated expression of this keratin with cytokeratin 20 is commonly used as a diagnostic marker for a variety of carcinomas. Applications Reported: This LP5K antibody has been reported for use in immunohistochemical and immunocytochemical staining. Applications Tested: This LP5K antibody has been tested immunocytochemistry on fixed and permeabilized MCF7 cells at less than or equal to 10 μg/mL. It is recommended that this antibody be carefully titrated for optimal performance in the assay of interest. This product has not been validated for flow cytometric analysis. Filter Recommendation: When using this eFluor 615 antibody conjugate, we recommend a filter that will capture the 615 emission wavelength (for example, Excitation 560/55, 585LP, Emission 645/75). A standard Alexa Fluor 594 filter is acceptable. Excitation: 595 nm; Emission: 615 nm. Filtration: 0.2 μm post-manufacturing filtered.

Frequently Asked Questions (FAQs)
Our options will depend on the samples you are analyzing.
If cell viability is not critical, you can store your stained samples at 4 degrees C or on ice overnight in the dark and analyze the following day.
For samples stained with eFluor organic fluorochromes, we recommend that cells be suspended in 100 uL of Flow Cytometry Staining Buffer (Cat. No. 00-4222) and 100 uL of eBioscience IC Fixation Buffer (Cat. No. 00-8222); samples can be incubated for up to 3 days at 4 degrees C in the dark. Alternatively, the 1-step Fix/Lyse Solution (Cat. No. 00-5333) can be used. This is a great option when working with whole blood but also works for other cell types.
The eFluor Organic fluorochromes and eVolve QDots can be used with flow staining buffers containing PBS and protein.
The eFluor Organic Dyes (eFluor 450, APC-eFluor 780, PerCP-eFluor 710, eFluor 710) are conventional fluorochromes. In contrast, the eVolve line of products are Quantum dots.
