Description

A single non-glycosylated polypeptide chain containing 134 amino acids corresponding to Galectin-1 Source: E. coli

Uniprot ID: P09382

Amino Acid Sequence: ACGLVASNLN LKPGECLRVR GEVAPDAKSF VLNLGKDSNN LCLHFNPRFN AHGDANTIVC NSKDGGAWGT EQREAVFPFQ PGSVAEVCIT FDQANLTVKL PDGYEFKFPN RLNLEAINYM AADGDFKIKC VAFD

This lyophilized preparation is stable for 12 months from date of receipt at -20 to -70 degrees C, preferably desiccated. Upon reconstitution, the preparation can be stored for 1 month at 2-8 degrees C under sterile conditions, and for 3 months at -20 degrees C to -70 degrees C. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. Stock solutions should be aliquoted and stored at < -20 degrees C. Further dilutions should be made in appropriate buffered solutions

Purity

>95%, by SDS-PAGE and HPLC

Endotoxin Level

Less than 0.1 EU/ug of Galectin-1 as determined by LAL method.

Predicted Molecular Mass

14.6 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Activity

Galectin 1 protein is fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human blood monocytes is in a concentration range of 1.0-10 ng/ml.

Background: Galectin-1

Human Galectin-1 also named BHL, Galaptin, GBP, L-14 and LGALS1, is belonging to the galectins family and it is encoded by the LGALS1 gene in human. Galectin-1 is expressed by the endometrial stromal cells throughout the menstrual cycle. Galectin-1 contains a single carbohydrate recognition domain through which it can bind glycans both as a monomer and as a homodimer. Dimers are non-covenantly bound and will spontaneously disassociate in low concentration. Galectin-1 may act as an autocrine negative growth factor that regulates cell proliferation. Galectin-1 is thought to play a role in the immunosuppression required for a successful pregnancy. Human Galectin-1 shares 88 %-90 % amino acid sequence identity with rat and mouse.
