The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB 1/500 - 1/2000. Detects a band of approximately 22 kDa (predicted molecular weight: 20 kDa).
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval via the pressure cooker method before commencing with IHC staining protocol.
ICC 1/100 - 1/250.
  • Application notes
    Is unsuitable for Flow Cyt or IP.
  • Target

    • Function
      May contribute to the transparency and refractive index of the lens.
    • Tissue specificity
      Lens as well as other tissues.
    • Involvement in disease
      Defects in CRYAB are the cause of myofibrillar alpha-B crystallin-related (MFM-CRYAB) [MIM:608810]. A neuromuscular disorder that results in weakness of the proximal and distal limb muscles, weakness of the neck, velopharynx and trunk muscles, hypetrophic cardiomyopathy, and cataract in a subset of patients.
    • Sequence similarities
      Belongs to the small heat shock protein (HSP20) family.
    • Cellular localization
      Cytoplasm. Nucleus. Translocates to the nucleus during heat shock and resides in sub-nuclear structures known as SC35 speckles or nuclear splicing speckles.
