Haptoglobin (Hp) is a blood plasma protein that forms high affinity complexes with free hemoglobin that is released from erythrocytes. In hemolytic anaemia, haptoglobin levels decrease as high levels of hemoglobin are released from the lysed erythrocytes.
- Target Species
- Product Form
- Purified protein from human plasma - lyophilized
- Reconstitute with sterile PBS (0.15M NaCl). Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution.

- None present
- >95% by SDS PAGE
- Store at -70oC.
Storage in frost-free freezers is not recommended.
This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the protein.
