| Purity | Greater than 95.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. | Source | Escherichia Coli. |
| Phycical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. | Shipping Condition | Shipped at Room temp. |
| Synonyms | Galectin-7; Gal-7; HKL-14; PI7; p53-induced gene 1 protein; LGALS7; PIG1; LGALS7B; GAL7; LGALS7A. | ||
| 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. | ||
| Solubility | It is recommended to reconstitute the lyophilized Galectin-7 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. | ||
| 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. | ||
| Biological Activity | The ED50 of Galectin-7 as determined by hemagglutination test is 0.75~3 µg/ml. | ||
| Formulation | LGALS7 was lyophilized from a concentrated (1mg/ml) solution in 20mM PBS, pH 7.4. | ||
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.
The ED50 of Galectin-7 as determined by hemagglutination test is 0.75~3 µg/ml.
