Mouse myeloma cell line NS0-derived recombinant mouse Cystatin E/M
Accession # NP_082899
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.


Recommended Concentration
Western Blot
1 µg/mL
Recombinant Mouse Cystatin E/M (Catalog # 1284-PI)
25 µg/mL
Conditioned cell culture medium spiked with Recombinant Mouse Cystatin E/M (Catalog # 1284-PI), see our available Western blot detection antibodies
Measured by its ability to neutralize Recombinant Mouse Cystatin E/M (0.64 µg/mL, Catalog # 1284-PI) inhibition of Papain (0.1 µg/mL) cleavage of the fluorogenic peptide substrate Z-FR-AMC (100 µM, Catalog # ES009). The Neutralization Dose (ND50) is typically 7 µg/mL.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Background: Cystatin E/M

Cystatin E/M is a member of family 2 of the cystatin superfamily (1 ‑ 6). It is required for viability and for correct formation of cornified layers in the epidermis and hair follicles, as ichq mice with a null mutation in the cystatin E/M gene have defects in epidermal cornification and die between 5 and 12 days of age (7). Cystatin E/M expression and function may not be limited to cutaneous epithelia. For example, it is found in rat brain and is induced during neuronal cell differentiation (8). In addition to being a cysteine protease inhibitor, the human cystatin E/M is also a substrate for transglutaminases (9).
