Galectin-1/LGALS1 Protein, Mouse (HEK293, Fc)

Galectin-1/LGALS1 protein is a β-galactoside-binding lectin that regulates apoptosis, cell proliferation, and differentiation by inhibiting CD45 protein phosphatase. It prevents Lyn kinase dephosphorylation, induces T cell apoptosis as a homodimer, and interacts with CD2, CD3, CD4, CD6, CD7, CD43, ALCAM and CD45. Galectin-1/LGALS1 Protein, Mouse (HEK293, Fc) is the recombinant mouse-derived Galectin-1/LGALS1 protein, expressed by HEK293 , with N-hFc labeled tag. The total length of Galectin-1/LGALS1 Protein, Mouse (HEK293, Fc) is 134 a.a., with molecular weight of 45-52 kDa.

Galectin-1/LGALS1 Protein functions as a versatile lectin with a high affinity for beta-galactoside and a diverse range of complex carbohydrates. Its pivotal role extends to the regulation of apoptosis, cell proliferation, and cell differentiation. Notably, Galectin-1/LGALS1 acts as an inhibitor of CD45 protein phosphatase activity, thereby preventing the dephosphorylation of Lyn kinase. Furthermore, it serves as a potent inducer of T-cell apoptosis and exists as a homodimer. The protein engages in various interactions, binding to LGALS3BP and interacting with cell surface proteins such as CD2, CD3, CD4, CD6, CD7, CD43, ALCAM, and CD45. Galectin-1/LGALS1 also forms associations with laminin through poly-N-acetyllactosamine binding and interacts with SUSD2. A noteworthy interaction occurs with the cargo receptor TMED10, facilitating translocation from the cytoplasm into the endoplasmic reticulum-Golgi intermediate compartment (ERGIC) and subsequent secretion.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
