Recombinant Human Galectin-7

Description :

Recombinant Human Galectin-7 is produced by our E.coli expression system and the target gene encoding Met1-Phe136 is expressed.

Formulation :

Lyophilized from a 0.2 米m filtered solution of 20mM Tris, 150mM NaCl, 1mM EDTA, 5% Trehalose, pH 8.0.

Purity :

Greater than 95% as determined by reducing SDS-PAGE.

Endotoxin :

Less than 0.1 ng/米g (1 EU/米g) as determined by LAL test.

Reconstitution :

Always centrifuge tubes before opening. Do not mix by vortex or pipetting.It is not recommended to reconstitute to a concentration less than 100 米g/ml.Dissolve the lyophilized protein in distilled water.Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

Storage :

Lyophilized protein should be stored at < -20～C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7～C for 2-7 days.Aliquots of reconstituted samples are stable at < -20～C for 3 months.

Background :

The Galectin family of proteins, with specificity for Nacetyllactosamine containing glycoproteins, consists of beta-galactoside binding lectins containing homologous carbohydrate recognition domains (CRDs).They also possess hemagglutination activity, which is attributable to their bivalent carbohydrate binding properties. Galectins are active both intracellularly and extracellularly. Although they are localized primarily in the cytoplasm and lack a classical signal peptide; they can be secreted by one or more as yet unidentified non-classical secretory pathways. They have diverse effects on many cellular functions including adhesion, migration, polarity, chemotaxis, proliferation, apoptosis, and differentiation. Galectins may play a key role in many pathological states, including autoimmune diseases, allergic reactions, inflammation, tumor cell metastasis, atherosclerosis, and diabetic complications.
