Tag Info: Tag-Free

Expression Region: 1-175aa

Sequence Info: Full Length

MW: 20.2 kDa

Purity: Greater than 85% as determined by SDS-PAGE.

Relevance: May contribute to the transparency and refractive index of the lens. Has chaperone-like activity, preventing aggregation of various proteins under a wide range of stress conditions.

Reference: "The major in vivo modifications of the human water-insoluble lens crystallins are disulfide bonds, deamidation, methionine oxidation and backbone cleavage." Hanson S.R.A., Hasan A., Smith D.L., Smith J.B. Exp. Eye Res. 71:195-207(2000)

Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20?/-80?. The shelf life of lyophilized form is 12 months at -20?/-80?.

Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4? for up to one week.

Function: May contribute to the transparency and refractive index of the lens. Has chaperone-like activity, preventing aggregation of various proteins under a wide range of stress conditions.

Involvement in disease: Myopathy, myofibrillar, 2 (MFM2); Cataract 16, multiple types (CTRCT16); Myopathy, myofibrillar, fatal infantile hypertonic, alpha-B crystallin-related (MFMFIH-CRYAB); Cardiomyopathy, dilated 1II (CMD1II)

Subcellular Location: Cytoplasm, Nucleus

Protein Families: Small heat shock protein (HSP20) family

Tissue Specificity: Lens as well as other tissues (PubMed:838078, PubMed:2387586). Expressed in myocardial tissue (PubMed:28493373).

Paythway: Proteinprocessinginendoplasmicreticulum

Form: Liquid or Lyophilized powder

Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20?/-80?. Our default final concentration of glycerol is 50%. Customers could use it as reference.
