Allergen:rBla g 2 (Blattella germanica allergen 2 )

Unit:250μg

Source:P. pastoris (clone NIG rBla g 2, glycosylation site N93Q mutated)

Mol. Wt:~37 kD

Purification:Purified from Pichia pastoris culture supernatant by monoclonal antibody affinity chromatography. Purity by silver stained SDS-PAGE > 95%.

Concentration:

See product insert. 

Formulation:

Preservative and carrier-free in phosphate buffered saline, pH 7.4. Filtered through 0.22 μm filter.

Storage:Store at -20oC.

Notes:(1) One glycosylation site was removed in this recombinant leaving two glycosylation sites. The recombinant is glycosylated and has a slightly higher MW than natural. Bla g 2 (36kD).

(2) This recombinant form was used to determine the crystal structure of Bla g 2.

Genbank:U28863 Mutation N93Q, substituted cag (Q) for aac (N)

PDB:1YG9, 2NR6 (with Fab-7C11), X-ray crystal structures

Product Resources:Recombinant Bla g 2 Certificate of Analysis

Allergens are provided for research and commercial use in vitro:  not for human in vivo or therapeutic use.
