Scientific Background
Mouse 2B4/CD244 Protein — also known as CD244; NK cell type I receptor protein 2B4; NKR2B4; Natural killer cell receptor 2B4; SLAM family member 4; SLAMF4; Sign — Natural killer cell receptor 2B4 (2B4/CD244)is a 66 kDa type I transmembrane glycoprotein in the SLAM subgroup of the CD2 protein family. SLAM family proteins have an extracellular domain (ECD) with two or four Ig-like domains and at least two cytoplasmic immunoreceptor tyrosine-based switch motifs (ITSMs). 2B4 interacts with CD48, while other SLAM family proteins interact in a homophilic manner. The mouse 2B4 cDNA encodes a 397 amino acid (aa) precursor that includes a 19 aa signal sequence, a 207 aa ECD with one Ig-like V-type and one C2-type Ig-like domain, a 21 aa transmembrane segment, an
Research into Mouse 2B4/CD244 Protein supports investigations in cellular signaling and fundamental cell biology, with implications for cell signaling pathways.
Product Description
HEK293 Mammalian CellsC-His
Produced in HEK293 Mammalian Cells, preserving native glycosylation patterns and supporting biological activity in cell-based assays.
The C-His enables single-step affinity purification and can also serve as a handle for direct detection using anti-tag antibodies without target-specific reagents.
Expression region: Gln20-Asn221.

This protein is produced in HEK293 mammalian cells. Mammalian expression preserves glycosylation and folding closest to the native protein, supporting biological activity in cell assays.
Purity: > 95% as determined by reducing SDS-PAGE., confirmed by reducing SDS-PAGE. Endotoxin level: < 1.0 EU per μg of the protein as determined by the LAL method., measured by LAL assay — critical for cell-based studies. Identity is verified by peptide mapping or N-terminal sequencing on request.
Yes — biological activity is confirmed per lot. Activity data: Not validated for activity. Run a titration in your own system to establish optimal working concentration before committing all samples.
Reconstitution: Please refer to the printed manual for detailed information.. Storage: 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-. Avoid repeated freeze-thaw — each cycle risks partial denaturation.
This protein is validated for ELISA, Functional Assay (In Vitro). It is commonly used as an ELISA standard, binding partner in SPR/BLI, or stimulant in cell-based functional assays. Validate performance in your specific format before use in critical experiments.
