Soy PE LPI; PE (soy)	Phospholipase	Infection
Phosphatidylethanolamine is the most abundant phospholipid in prokaryotes and the second most abundant found in the membrane of mammalian, plant, and yeast cells, comprising approximately 25% of total mammalian phospholipids. In the brain, phosphatidylethanolamine comprises almost half of the total phospholipids. It is synthesized mainly through the cytidine diphosphate-ethanolamine and phosphatidylserine decarboxylation pathways, which occur in the endoplasmic reticulum (ER) and mitochondrial membranes, respectively. It is a precursor in the synthesis of phosphatidylcholine and arachidonoyl ethanolamide and is a source of ethanolamine used in various cellular functions. In E. coli, phosphatidylethanolamine deficiency prevents proper assembly of lactose permease, suggesting a role as a lipid chaperone. It is a cofactor in the propagation of prions in vitro and can convert recombinant mammalian proteins into infectious molecules even in the absence of RNA. This product contains phosphatidylethanolamine molecular species with variable fatty acyl chain lengths at the sn-1 and sn-2 positions.

As a homotetramer, LacI finely tunes lactose metabolism, orchestrating regulatory mechanisms in response to the cellular environment. LacI Protein, E.coli (Q360QC, His) is the recombinant E. coli-derived LacI protein, expressed by E. coli , with N-10*His labeled tag and Q360QC mutation.

	LALBA Protein, Human (HEK293, His) rHuAlpha-lactalbumin/LALBA, His; lactose synthase B protein; Lysozyme-like protein 7; LALBA; LYZL7	Human	HEK293
	LALBA proteins are regulatory subunits of lactose synthase and play a key role in altering the substrate specificity of mammary galactosyltransferase. This modification allows galactosyltransferase to utilize glucose, promoting the synthesis of lactose - the main milk carbohydrate. LALBA Protein, Human (HEK293, His) is the recombinant human-derived LALBA protein, expressed by HEK293 , with C-6*His labeled tag.

	Galectin-4 Protein, Mouse (HEK293, His) LGALS4; L36LBP; Gal-4; Antigen NY-CO-27; lactose-binding lectin 4	Mouse	HEK293
	Galectin-4 is a lactose-binding protein belonging to the galectin family that exhibits specific affinities for a range of structurally related sugars. This multifunctional protein is noteworthy for its functionality as a monomer, highlighting its individual molecular structure and suggesting that it may exert its biological effects through independent interactions rather than as part of a larger complex. Galectin-4 Protein, Mouse (HEK293, His) is the recombinant mouse-derived Galectin-4 protein, expressed by HEK293 , with N-His labeled tag.

	Animal-Free Galectin-2/LGALS2 Protein, Human (His) Galectin; Lgals2; Beta-gActoside-binding lectin L-14-II; GAL2; Gal-2; galectin 2; Galectin2; Galectin-2; HL14gal-2; lactose-binding lectin 2; lectin, gActoside-binding, soluble, 2; MGC75071; S-Lac lectin 2	Human	E. coli
	The Galectin-2 (LGALS2) protein binds with affinity to β-galactopyranoside and forms homodimers, indicating a basic functional organization. Although the physiological role is unclear, β-galactoside binding of LGALS2 suggests a possible involvement in recognition of specific carbohydrates. Animal-Free Galectin-2/LGALS2 Protein, Human (His) is the recombinant human-derived animal-FreeGalectin-2/LGALS2 protein, expressed by E. coli , with N-His labeled tag. This product is for cell culture use only.
