Introduction

LGALS8 is a prostate-specific antigen that is solely overexpressed in malignant tumors and thus is a supplementary specific identifier of malignancies. LGALS8 is part of the galectin gene family which facilitates both cell-cell and cell matrix interactions in a method parallel to the selectin subgroup of C-type lectins.

Description

LGALS8 mouse Recombinant produced E. coli is a single polypeptide chain containing 339 amino acids (1-316) and having a molecular mass of 38kDa.
LGALS8 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

Source

Escherichia Coli.

Physical Appearance

Sterile Filtered colorless solution.

Formulation

The LGALS8 solution (0.5mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 0.15M NaCl, 20% glycerol and 1mM DTT.

Stability

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.

Purity

Greater than 90.0% as determined by SDS-PAGE.

Assay Conditions

1. Mix equal volumes of human blood and Alsever’s solution (pH 7.0). (Alsever’s solution: NaCl 0.42g, Sodium citric acid 0.8g, Citric acid 0.055g, D-glucose 2.05g in DW100 ml).
2. Centrifuge at 15000rpm for 10 minutes and wash 4 times with PBS.
3. Dilute packed cells in a 0.5mg/ml trypsin-EDTA solution to give 4% red cell suspension.
4. Incubate for 1 hour at 37°C and wash 4 times with PBS.
5. Dilute packed cells in PBS to give a 4% red cell suspension.
6. Load 50µl of 0.5%BSA-in-0.15M-NaCl solution and 25µl of 4%-Red-Cell-in-PBS in U shaped wells.
7. Add 25µl of serial diluted galectin protein in PBS to each well plate (Round bottom 96 well plate).
8. Incubate for 30 minutes at room temperature to observe visible agglutination.

Biological Activity

The ED50 for this effect is ≤ 2ug/ml. Measured by its ability to agglutinate human red blood cells.
