  • FunctionType V collagen is a member of group I collagen (fibrillar forming collagen). It is a minor connective tissue component of nearly ubiquitous distribution. Type V collagen binds to DNA, heparan sulfate, thrombospondin, heparin, and insulin.
  • Involvement in diseaseEhlers-Danlos syndrome 1
    Ehlers-Danlos syndrome 2
  • Sequence similaritiesBelongs to the fibrillar collagen family.
    Contains 1 fibrillar collagen NC1 domain.
    Contains 1 laminin G-like domain.
  • DomainThe C-terminal propeptide, also known as COLFI domain, have crucial roles in tissue growth and repair by controlling both the intracellular assembly of procollagen molecules and the extracellular assembly of collagen fibrils. It binds a calcium ion which is essential for its function.
  • Post-translational
    Prolines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains.
    Sulfated on 40% of tyrosines.

  • ab7046 staining Collagen V in Human pancreas tissue by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded tissue sections). The sections were fixed in formaldehyde and subjected to heat-mediated antigen retrieval in citrate pH 6 prior to blocking with 0.25% casein for 5 minutes at 25°C. The primary antibody was diluted 1/75 in Tris--HCL and incubated with the sample for 30 minutes at 25°C. An HRP polymer-conjugated goat anti-rabbit antibody was used as the secondary antibody.

  • ab7046 staining Collagen V in Dog skeletal muscle tissue by Immunohistochemistry (Frozen sections). The sections were fixed in Acetone. The primary antibody was diluted 1/100 in 10% Normal Goat Serum (ab7481) in PBS-T and incubated with the sample for 12 hours at 4°C. A Rhodamine-conjugated Goat anti-Rabbit IgG was used as the secondary antibody, diluted 1/200.

You want to add glycerol to 50% before freezing. So what your labmate did (vial is 50% antibody, 50% glycerol) is correct.

Thank you for your patience in awaiting a response. Collagen V is over 400kDa.It is important to note that this product will not be supported in reduced conditions. Please use this product in non-reducing conditions. The public-facing data sheet. Thank...

Sorry, we really don't know if the antibody would detect the type specific collagen fragments.

The immunogen used to generate Rabbit polyclonal to Collagen V was Collagen Type V from adult human and bovine tissues. As the antibody is a polyclonal and was raised agaisnt the whole collagen molecule it will recognise a number of epitopes on the sur...
