Scientific Background
T-cell Immunoglobulin and Mucin Domain-containing Protein 4(TIM-4) belongs to the immunoglobulin superfamily, is a member of the TIM family of immune regulating proteins. TIMs are type I transmembrane proteins with one Ig-like V domain and one Ser/Thr-rich mucin domain. Structurally, TIM-4 is distinguished from other TIMs by the presence of an RGD motif in its Ig domain and the lack of a site for tyrosine phosphorylation in its cytoplasmic tail. The mucin domain in TIM-4 is larger than in TIM-1 or TIM-3. TIM-4 is expressed by macrophages and mature dendritic cells but not by lymphocytes.

Safety & Handling
STRICTLY FOR FURTHER SCIENTIFIC RESEARCH USE ONLY (RUO). NOT FOR USE IN DIAGNOSTIC OR THERAPEUTIC APPLICATIONS.
This protein was produced in Mammalian (HEK293) expression system. The expression system determines the protein post-translational modification profile, folding characteristics, and suitability for specific applications. Mammalian (HEK293) expression is used where native-like glycosylation is required; insect cell and E. coli systems are used for high-yield non-glycosylated production.
This product is supplied as lyophilized powder. Centrifuge the vial briefly before opening, then add the recommended volume of sterile water or the specified buffer and allow to dissolve at 4°C for 30 minutes without vortexing. Prepare single-use working aliquots in 0.1% BSA to minimise freeze-thaw losses of the bulk stock.
Endotoxin is < 1.0 EU per μg of the protein as determined by the LAL method., determined by the LAL chromogenic method. The <1.0 EU/µg specification ensures suitability for cell culture experiments, primary cell stimulation, and assays measuring immune activation or cytokine secretion, where endotoxin interference with NF-κB signalling is a concern.
This protein meets > 90% as determined by reducing SDS-PAGE purity as assessed by reducing SDS-PAGE. A gel image for each lot is included on the Certificate of Analysis. Contact technical support if purity >98% is required for biophysical measurements such as crystallography, ITC, or single-particle cryo-EM.
Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃. Reconstituted protein solution can be stored at 4-8℃ for 2-7 days. Aliquots of reconstituted samples are stable at < -20℃ for 3 months. Shelf life is 12 months from the date of receipt. Prepare small working aliquots to minimise freeze-thaw cycles of the bulk stock. Reconstituted lyophilized protein is stable for up to 3 months at −80°C in carrier protein.
