ML-WGA20 Wheat Germ Agglutinin EA 20 mg $190.71  $183.04  


Off-white lyophilised powder (affinity purified).

WGA is a non-blood group specific lectin.It has an affinity for oligomers of N-acetyl glucosamine with activities being reported as GlcNac < (GlcNAc)2< (GlcNAc)3 = (GlcNAc)4 < (GlcNAc)5a.

WGA at a concentration of 20 µg/mL gives a 50 % agglutination of a 2 % suspension of human red blood cells [type O(H)].Incubations performed for 1 h at room temperature in phosphate saline buffer (PBS).*

UV absorbance (in 10 mM phosphate buffer,pH 7.0) lmax= 275.8;lmin= 250.5 nm
Solubility:1 mg/mL in PBS (pH 7.2);~ 1 mg/mL in 1 mM Tris/HCl (pH 7.4);
> 10 mg/mL in 100 mM acetic acid.
