Alpha-crystallin A chain/CRYAA Protein, Human (His)
Based on 1 Customer Validation
Alpha-crystallin A chain/CRYAA Protein, Human (His) is a recombinant Alpha-crystallin A chain protein with a His tag. Alpha-crystallin A chain/CRYAA is a small heat shock protein and molecular chaperone that prevents nonspecific aggregation of denaturing proteins. Several point mutations in the alphaA-crystallin gene cause congenital human cataracts by unknown mechanisms.
- Species: Human
- Source: E. coli
-
Storage:Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Description
Alpha-crystallin A chain/CRYAA Protein, Human (His) is a recombinant Alpha-crystallin A chain protein with a His tag. Alpha-crystallin A chain/CRYAA is a small heat shock protein and molecular chaperone that prevents nonspecific aggregation of denaturing proteins. Several point mutations in the alphaA-crystallin gene cause congenital human cataracts by unknown mechanisms[1].
Background
Alpha-crystallin A chain/CRYAA Protein is a member of the small heat shock protein family that includes 10 proteins in humans characterized by a conserved-crystallin domain of ~90 amino acids in their C-terminal region. Point mutations in small heat shock protein genes are associated with pathological conditions such as cataracts and desmin-related myopathy[1].
Verified Bioactivity
Measured by its binding ability in a functional ELISA. When Recombinant CRYAA Human is used at 2 μg/mL can bind anti-CRYAA antibody. The ED50 for this effect is 1.405 μg/mL.

Product Properties
Lyophilized powder
1.Lyophilized from a 0.22 μm filtered solution of PBS, 2 mM EDTA, pH 8.0.
2.Lyophilized from a 0.22 μm filtered solution of PBS, pH 6.5, 8% trehalose.
Please refer to the lot-specific COA for specific buffer information.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
