Format
Lyophilized
Reconstitution
Allow the vial and reconstitution buffer to equilibrate to room temperature. Briefly centrifuge or tap down the vial to ensure that all lyophilized powder is collected at the bottom of the vial. For the reconstitution of this product, we recommend adding PBS or sterile water to achieve a final antibody concentration of 1 mg/mL. Allow the vial to reconstitute for 10-15 minutes at room temperature with gentle agitation. Avoid vigorous shaking that can cause foaming and antibody denaturation. Aliquot into volumes based on your experiment and store liquid protein at -20°C or -80°C for long time.
Buffer
Lyophilized from sterile PBS
Preservative
None
Storage
Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

Target

Full Name
Mannan Binding Lectin Serine Peptidase 2
Function
Serum protease that plays an important role in the activation of the complement system via mannose-binding lectin. After activation by auto-catalytic cleavage it cleaves C2 and C4, leading to their activation and to the formation of C3 convertase.

Involvement in disease
MASP2 deficiency (MASPD):
A disorder that results in autoimmune manifestations, recurrent severe infections, and chronic inflammatory disease.
PTM
The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains.
Activated by cleavage after Arg-444. The uncleaved zymogen is inactive towards synthetic substrates, but has sufficient activity to effect autocatalytic cleavage.
