Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.

Buffer

Lyophilized from a 0.2 μm filtered 20 mM Tris-HCl, 0.5 M NaCl, 6% Trehalose, pH 8.0

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Storage Condition

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.

Shelf Life

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

Lead Time

3-7 business days

Notes

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description

Myosin regulatory light chain 9 governs smooth muscle contraction through calcium-dependent phosphorylation and plays emerging roles in cancer cell motility and metastasis. This full-length mature protein (aa 2–172) demonstrates native-like folding, confirmed by functional ELISA showing dose-dependent antibody binding with an EC50 of 4.628–6.430 ng/mL when immobilized at 2 μg/mL, validating its conformational integrity for protein-protein interaction assays and antibody development workflows. The C-terminal His tag preserves the regulatory N-terminal phosphorylation sites critical for myosin II activation studies, while >95% purity and <1.0 EU/μg endotoxin meet the quality thresholds commonly required for cytoskeletal dynamics experiments and Western blot or immunofluorescence positive controls. Researchers investigating actomyosin contractility mechanisms, screening kinase inhibitors targeting MLCK-mediated phosphorylation, or mapping MYL9 binding partners in cancer invasion pathways will find this preparation supports quantitative binding assays and co-immunoprecipitation studies where conformational authenticity is essential.

Target Background

Function

Myosin regulatory subunit that plays an important role in regulation of both smooth muscle and nonmuscle cell contractile activity via its phosphorylation. Implicated in cytokinesis, receptor capping, and cell locomotion. In myoblasts, may regulate PIEZO1-dependent cortical actomyosin assembly involved in myotube formation.
