Allergen:rDer p 1 (Dermatophagoides pteronyssinus allergen 1) deglycosylated

Unit:250µg

Source:Pichia pastoris (clone N52Q, N-glycosylation site N52 mutated)

Mol. Wt:24 kD

Purification:

Purified from Pichia pastoris culture by multi-step column

chromatography. Purity on silver stained SDS-PAGE >95%.

Concentration:

See product insert. 

Formulation:

Preservative and carrier-free in sterile, 0.1M CAPS Buffer, pH 9.5. Filtered through 0.22 µm filter.

Storage:Store at -20ºC. Avoid freeze-thaw cycles.

Notes:1. A LoTox™ product: Endotoxin ≤ 0.03 EU/µg.

2. Mature form of rDer p 1; proregion removed with acid dialysis.

3. Cysteine protease activity (DTT dependent):

(see product insert) RFU @ 0.25µg/ml.

4. For stability purposes the product is shipped in CAPS Buffer pH9.5. It may be dialysed or diluted into a physiological buffer for cell culture purposes, but long term storage in PBS may cause

precipitation.

Genbank:U11695 = pro-Der p 1.0102 (difference is that in pro Der p 1.0105, V124 becomes A124)

PDB:1XKG, 2AS8, 3F5V X-ray crystal structures

Product Resources:Recombinant Der p 1 DG Certificate of Analysis

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