Overview

  • Product name

    Anti-OPA1 antibody [EPR11057(B)]
    See all OPA1 primary antibodies
  • Description

    Rabbit monoclonal [EPR11057(B)] to OPA1
  • Host species

    Rabbit
  • Specificity

    Recent lab testing showed that the antibody detects the band of interest at the proper molecular weight in several cell and tissue lysates. However, the antibody also detects a band at about 50kDa. We could not find in the literature any references on what this band could be. On our test, the 50kDa band detections decreased by decreasing the antibody concentration.
  • Tested applications

    Suitable for: WB, IHC-P, IHC-Frmore details
    Unsuitable for: ICC/IF or IP
  • Species reactivity

    Reacts with: Mouse, Human
    Predicted to work with: Rat, Sheep, Rabbit, Horse, Chicken, Guinea pig, Pig, Non human primates, Chinese hamster, Common marmoset, Bat
  • Immunogen

    Synthetic peptide within Human OPA1 aa 900 to the C-terminus. The exact sequence is proprietary.
    Database link: O60313

  • Positive control

    • WB: HeLa, HepG2, A431 cell lysates; IHC-P: Human brain and retina tissue; IHC-Fr: Mouse retina tissue.
  • General notes

    This product is a recombinant monoclonal antibody, which offers several advantages including:

    • - High batch-to-batch consistency and reproducibility
    • - Improved sensitivity and specificity
    • - Long-term security of supply
    • - Animal-free production

  • Application notes
    Is unsuitable for ICC/IF or IP.
  • Target

    • Function

      Dynamin-related GTPase required for mitochondrial fusion and regulation of apoptosis. May form a diffusion barrier for proteins stored in mitochondrial cristae. Proteolytic processing in response to intrinsic apoptotic signals may lead to disassembly of OPA1 oligomers and release of the caspase activator cytochrome C (CYCS) into the mitochondrial intermembrane space.
    • Tissue specificity

      Highly expressed in retina. Also expressed in brain, testis, heart and skeletal muscle. Isoform 1 expressed in retina, skeletal muscle, heart, lung, ovary, colon, thyroid gland, leukocytes and fetal brain. Isoform 2 expressed in colon, liver, kidney, thyroid gland and leukocytes. Low levels of all isoforms expressed in a variety of tissues.
    • Involvement in disease

      Defects in OPA1 are a cause of optic atrophy type 1 (OPA1) [MIM:165500]. OPA1 is a dominantly inherited optic neuropathy occurring in 1 in 50,000 individuals that features progressive loss in visual acuity leading, in many cases, to legal blindness.
      Defects in OPA1 are the cause of optic atrophy 1 with deafness (OPA1D) [MIM:125250]. Some individuals with mutations in OPA1 manifest also ophthalmoplegia and myopathy.
    • Sequence similarities

      Belongs to the dynamin family.
    • Post-translational
      modifications

      PARL-dependent proteolytic processing releases an antiapoptotic soluble form not required for mitochondrial fusion.
    • Cellular localization

      Mitochondrion inner membrane. Mitochondrion intermembrane space.
