Data sheet

Reconstitution 1mg/ml in PBS (after reconstitution).
Formulation LGALS7 was lyophilized from a concentrated (1mg/ml) solution in 20mM PBS, pH 7.4.
Solubility It is recommended to reconstitute the lyophilized Galectin-7 in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Purity Greater than 95.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
Description Galectin-7 Human Recombinant produced in E.Coli is a single, non-glycosylated, Polypeptide chain containing 135 amino acids and having a molecular mass of 15kDa.The LGALS7 is purified by proprietary chromatographic techniques.
Protein Background Galectins are a family of animal lectins with an affinity for beta-galactosides. This family has at least 14 identified members. Galectins share similarities in the CRD (the carbohydrate recognition domain). Galectins are synthesized as cytosolic proteins. Though localized principally in the cytoplasm and lacking a classical signal peptide, galectins can also be stimulated to secretion by non-classical pathways or alternatively targeted to the nucleus. Galectins are involved in modulating cell-cell and cell-matrix interactions. Human Galectin-7 belongs to the prototypical Galectins containing a single CRD, which is initially identified in human epidermis as a monomer. The Galectin-7 expression is induced by tumor suppressor protein p53 and associated with apoptosis. Galectin-7 is a pro-apoptotic protein which functions intracellularlly upstream of JNK activation and mitochondrial cytochrome c release. The correlation of Galectin-7 with the UV-induced apoptosis of keratinocytes presents a critical mechanism in the maintenance of epidermal homeostasis. Human Galectin-7 is localized in both nucleus and cytoplasm.
Expression host Escherichia Coli.
Synonyms Galectin-7, Gal-7, HKL-14, PI7, p53-induced gene 1 protein, LGALS7, PIG1, LGALS7B, GAL7, LGALS7A.
Reagent Appearance Sterile Filtered White lyophilized (freeze-dried) powder.
Stability Lyophilized LGALS7 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Galectin-7 should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles.
Amino acid sequence The sequence of the first five N-terminal amino acids was determined and was found to be Ser-Asn-Val-Pro-His.
Biological Activity The ED50 of Galectin-7 as determined by hemagglutination test is 0.75~3 ug/ml.
Antibody Properties Reconstitute with of H20. Mix gently, wash the sides of the vial and wait 30-60 seconds before use.
Available Conjugates Cytotoxic and staining antibody. For staining, use 10ml/1,000,000 cells. Titer for cytotoxicity should be determined by the investigator.
Immunological function This antibody is also available conjugated to biotin and FITC.
Product Description Recognizes most MHC class II haplotypes (b,f,p,q,r,s,u,v), but weak against I-Ak.
