• Product name

    Anti-Hsp27 (phospho S86) antibody
    See all Hsp27 primary antibodies
  • Description

    Rabbit polyclonal to Hsp27 (phospho S86)
  • Host species

  • Specificity

    Lysates prepared from NIH3T3 cells were immunoblotted in the presence of non-phosphopeptide corresponding to the immunogen, a generic phosphoserine-containing peptide or the phosphopeptide immunogen. The data show that only the peptide corresponding to the mouse phospho S86 HSP27 blocks the antibody signal, thereby demonstrating the specificity of the antibody. The signal was completely removed by lambda phosphatase treatment demonstrating that the antibody interacts specifically with the phosphorylated protein.

  • Involvement in disease

    Defects in HSPB1 are the cause of Charcot-Marie-Tooth disease type 2F (CMT2F) [MIM:606595]. CMT2F is a form of Charcot-Marie-Tooth disease, the most common inherited disorder of the peripheral nervous system. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathy or CMT1, and primary peripheral axonal neuropathy or CMT2. Neuropathies of the CMT2 group are characterized by signs of axonal regeneration in the absence of obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and progressive distal muscle weakness and atrophy. Nerve conduction velocities are normal or slightly reduced. CMT2F onset is between 15 and 25 years with muscle weakness and atrophy usually beginning in feet and legs (peroneal distribution). Upper limb involvement occurs later. CMT2F inheritance is autosomal dominant.
    Defects in HSPB1 are a cause of distal hereditary motor neuronopathy type 2B (HMN2B) [MIM:608634]. Distal hereditary motor neuronopathies constitute a heterogeneous group of neuromuscular disorders caused by selective impairment of motor neurons in the anterior horn of the spinal cord, without sensory deficit in the posterior horn. The overall clinical picture consists of a classical distal muscular atrophy syndrome in the legs without clinical sensory loss. The disease starts with weakness and wasting of distal muscles of the anterior tibial and peroneal compartments of the legs. Later on, weakness and atrophy may expand to the proximal muscles of the lower limbs and/or to the distal upper limbs.
  • Sequence similarities

    Belongs to the small heat shock protein (HSP20) family.
  • Post-translational

    Phosphorylated in MCF-7 cells on exposure to protein kinase C activators and heat shock.
  • Cellular localization

    Cytoplasm. Nucleus. Cytoplasm > cytoskeleton > spindle. Cytoplasmic in interphase cells. Colocalizes with mitotic spindles in mitotic cells. Translocates to the nucleus during heat shock and resides in sub-nuclear structures known as SC35 speckles or nuclear splicing speckles.

Thank you for enquiry. Following contact with the source of this antibody I have determined that this antiserum was produced against a chemically synthesized phosphopeptide derived from a region of mouse HSP25 that contains serine 86. The synthetic peptide used is approximately 10 amino acid residues with the phospho site around the center of the sequence. Whilst the exact sequence is considered to be proprietary I have performed an alignment of the Rattus sequence and the murine sequence and determined that the 10 amino acids either side of serine 86 are identical (PAFSRALNRQLSSGVSEIRQTA) and therefore the immunogen must be identical between rat and mouse. This strongly suggests that the antibody would work in rat. I have updated our datasheets to reflect this. The alignment that I have just performed can be accessed at: http://www.ebi.ac.uk/cgi-bin/jobresults/clustalw/clustalw-20051209-10471217.aln? I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

Thank you for your enquiry. All the information we have on species cross reactivity is specified on the datasheet, these are updated as soon as any new information is brought to our attention. As far as we are aware, cross reactivity with rat has not yet been tested for use with ab17938. Given the potential similarity in the epitope I am going to submit an enquiry to the source of the antibody to determine whether the immunogen was identical. This will provide an excellent indication as to how the antibody might behave against rat. Should you decide to go ahead and purchase this product, please let us know how you get on by submitting an Abreview and in return we will award you 50 Abcam Points, which can be redeemed on a number of rewards (a further 100 points will be offered for an image). Please let me know if you require any further assistance.
