(gē-ăr′dĭnz)
Proteins of the sucker disks of Giardia lamblia (also known as G. duodenalis) that help the parasite adhere to the lining of the small intestine.

Giardins, unique component of the cytoskeleton of Giardia, have been identified as four major classes: alpha ([alpha]), beta ([beta]), gamma ([gamma]), and delta ([delta]) [5].
The localization experiments showed that a few [alpha]-giardins ([alpha]-3, [alpha]-5, and [alpha]-17) are localized in the adhesive disc; [alpha]-15 and [alpha]-16 giardins had a patchy distribution along the plasma membrane, while the others ([alpha]-1, [alpha]-2, [alpha]-6, [alpha]-7.2, [alpha]-7.3, [alpha]- 9, [alpha]-10, and [alpha]-14) were mainly distributed in plasma membrane, adhesive disc, flagella, or cytoplasm.
For purification of soluble [alpha]-13 giardins, BL21 (DE3) cells harboring pET-28a(+)-g-[alpha]13 were cultured in 1000 mL of LB medium for 5h at 25[degrees]C with 50 [micro]g/mL kanamycin.
Four classes of giardins, [alpha], [beta], [gamma], and [delta], have been identified as cytoskeleton components of the Giardia.
Different giardins have different subcellular localizations in G.

In this research work, we proceed to provide new reports on prokaryotic expression of [alpha]-13 giardin gene and its intracellular localization in G.
Two primers specific to [alpha]-13 giardin gene, A13E (5'-CGG GAT CCA TGC CTG TTC TGA CCC C37) with Bam HI restriction site (underlined) and A13F (57CCC AAG CTT CTA ATC CAC ATC CCA GAG CC-3') with Hind III restriction site (underlined), were designed based on the G.
Expression of [alpha]-13 Giardin. The recombinant plasmids were transformed into E.
The [alpha]-13 giardin proteins were detected using the ECL Plus Western blotting detection system (Tiannon, Shanghai, China) by rabbit anti-His tag monoclonal antibody (diluted 1: 2000) and horseradish peroxidase- (HRP-) labeled goat anti-rabbit IgG antibody (Transgen, Beijing, China) at dilution of 1: 3000.
Total trophozoite extract and the purified [alpha]-13 giardin fusion protein were subjected to 12% SDS-PAGE and transferred to nitrocellulose membrane.
Primary antibody was diluted in dilution buffer (at 1: 500), after reacting with the rabbit anti-[alpha]13- giardin antiserum for 1 h; the samples were washed three times with PBS and then incubated for 1 h in the dark with Alexa Fluor 488 anti-rabbit IgG (H+L) from goat (1:200) (Beyotime, Jiangsu, China) at room temperature.
