产品名称:Recombinant protein L;重组蛋白 L

技术参数:

Accession D6S9W1
Source Escherichia coli.

Protein per Gram Powder See Label.
Concentration for 1 unity DO at 280 nm 1.133 mg/ml
Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder.
Purity > 97 % by SDS-PAGE and SEC-HPLC analyses.
Specificity The recombinant Protein L is a genetically engineered protein containing 5 IgG-binding regions of protein L. Cell wall binding region, cell membrane binding region and albumin binding region have been removed from the recombinant Protein L to ensure the maximum specific IgG binding. The recombinant Protein L is ideal for purification of polyclonal or monoclonal IgG antibodies. Protein L binds to human, mouse, rat and pig IgG.
Endotoxin Level Less than 0.1 EU/μg of Protein L as determined by LAL method.
Formulation Lyophilized from additive free solution.
Stability & Storage Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
- 12 months from date of receipt, -20 to -70 °C as supplied.
- 1 month, 2 to 8 °C under sterile conditions after reconstitution.
- 3 months, -20 to -70 °C under sterile conditions after reconstitution.
Reconstitution Dissolve in distilled water or saline.
Background Recombinant Protein L contains 5 kappa-binding domain. Protein L has the unique ability to bind through kappa light chain interactions without interfering with the antibody’s antigen-binding site. This gives Protein L the ability to bind a wider range of Ig classes and subclasses than other antibody-binding proteins.
