ターゲット情報

  • 機能

    Type IV collagen is the major structural component of glomerular basement membranes (GBM), forming a 'chicken-wire' meshwork together with laminins, proteoglycans and entactin/nidogen.
    Arresten, comprising the C-terminal NC1 domain, inhibits angiogenesis and tumor formation. The C-terminal half is found to possess the anti-angiogenic activity. Specifically inhibits endothelial cell proliferation, migration and tube formation. Inhibits expression of hypoxia-inducible factor 1alpha and ERK1/2 and p38 MAPK activation. Ligand for alpha1/beta1 integrin.
  • 組織特異性

    Highly expressed in placenta.
  • 関連疾患

    Defects in COL4A1 are a cause of brain small vessel disease with hemorrhage (BSVDH) [MIM:607595]. Brain small vessel diseases underlie 20 to 30 percent of ischemic strokes and a larger proportion of intracerebral hemorrhages. Inheritance is autosomal dominant.
    Defects in COL4A1 are the cause of hereditary angiopathy with nephropathy aneurysms and muscle cramps (HANAC) [MIM:611773]. The clinical renal manifestations include hematuria and bilateral large cysts. Histologic analysis revealed complex basement membrane defects in kidney and skin. The systemic angiopathy appears to affect both small vessels and large arteries.
    Defects in COL4A1 are a cause of porencephaly familial (PCEPH) [MIM:175780]. Porencephaly is a term used for any cavitation or cerebrospinal fluid-filled cyst in the brain. Porencephaly type 1 is usually unilateral and results from focal destructive lesions such as fetal vascular occlusion or birth trauma. Type 2, or schizencephalic porencephaly, is usually symmetric and represents a primary defect or arrest in the development of the cerebral ventricles.
  • 配列類似性

    Belongs to the type IV collagen family.
    Contains 1 collagen IV NC1 (C-terminal non-collagenous) domain.
  • ドメイン

    Alpha chains of type IV collagen have a non-collagenous domain (NC1) at their C-terminus, frequent interruptions of the G-X-Y repeats in the long central triple-helical domain (which may cause flexibility in the triple helix), and a short N-terminal triple-helical 7S domain.
  • 翻訳後修飾

    Lysines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in all cases and bind carbohydrates.
    Prolines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains.
    Type IV collagens contain numerous cysteine residues which are involved in inter- and intramolecular disulfide bonding. 12 of these, located in the NC1 domain, are conserved in all known type IV collagens.
    The trimeric structure of the NC1 domains is stabilized by covalent bonds between Lys and Met residues.
    Proteolytic processing produces the C-terminal NC1 peptide, arresten.

  • Immunohistochemical analysis of paraffin-embedded mouse pancreas tissue stained for Collagen IV using ab19808.

    Endocrine-cells coated with a layer of extracellular matrix (P1). Immunohistochemical staining for Insulin (green), glucagon (red) and collagen IV (yellow) is shown. Note that intra-islet blood vessels are also associated with the extracellular matrix. Scale bar is 50 µm.

    The primary antibodies were detected using different combinations of Cy2, Cy5 and Texas Red-conjugated secondary antibodies and the image was captured via confocal microscopy.

  • Ovaries were dissected from PND 23–29 mice, embedded in Cryomatrix and fixed with 4% formaldehyde for 10 minutes, rinsed three times with phosphate-buffered saline (PBS), then permeabilized with 0.1% Triton X-100 for 15 minutes. Sections were again rinsed three times with PBS, blocked for 30 minutes with blocking solution (5% BSA in 0.1% Triton X-100), then rinsed three times with blocking solution. The tissue was then incubated for one hour with ab19808 at 1/400 dilution. Sections were then rinsed three times in blocking solution and incubated in secondary antibody (FITC-conjugated goat anti-rabbit secondary antibody).

    Immunofluorescence with ab19808 was used to detect Collagen IV localization to the follicular basal lamina (white filled arrowhead), focimatrix (open arrowhead), thecal matrix (asterix), and endothelial basal lamina of stromal blood vessels (square).

  • ab19808 staining Collagen IV in murine brain tissue/ human xenograft tissue by Immunohistochemistry. Tissue was fixed in AFA (alcohol-formal-acetate) and a heat mediated antigen retrieval step was performed using Tris-EDTA pH 9. Samples were then blocked using 3% BSA for 30 minutes at 20°C and then incubated with ab19808 at a 1/500 dilution for 1 hour and 30 minutes. The secondary used was an undiluted HRP-conjugated goat polyclonal. Left side: normal mouse brainRight side: human glioblastoma xenograft

Question
Answer

Thank you for your recent telephone enquiry. i am sorry it has taken some time to obtain this information for you from the originator.

I am sorry to confirm that in this particular case, the buffer components are proprietary. We are able to inform you that it includes a phosphate based salt (not PBS or TBS) which promotes the tissue activity and the quality of images in immunohistochemistry assays. No additional proteins or amines are added to the buffer.

I hope this will be helpful to you. If you have any further questions, please do not hesitate to contact us.

Answer

Thank you for contacting us.

There isn’t a specific protocol for performing WB with this antibody. We recommend using reducing and denaturing conditions unless otherwise stated on the datasheet. For this particular antibody there isn’t a specific recommended dilution, so I would suggest trying several dilutions to determine the one that works better for your experiment. For purified antibodies, the starting recommended concentration is 1ug/ml.

In case it could be useful, I include the link to our protocol’s page, where you can find all the information relative to Western Blot protocols:

https://www.abcam.com/index.html?pageconfig=popular_protocols

In any case, all of our products are covered by our Abpromise® guarantee, which ensures that you can trust our products, and they should work in the tested species and applications stated on the datasheet, or we will offer a replacement, credit, or refund, if reported within 6 months of purchase.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Answer

Thanks for your call today and for your questions about our collagen IV antibodies.
As we discussed, I would still recommend trying ab6586 with your standard Western blotting conditions. We recommend non-denatured conditions because the affinity of the antibody is higher in these conditions, but I did find user-submitted Abreviews in which the antibody was used in denatured conditions and the results were satisfactory (rated "Excellent" by the reviewers)-
https://www.abcam.com/index.html?datasheet=6586&tab=abreviews&intabreviewid=7703
https://www.abcam.com/index.html?datasheet=6586&tab=abreviews&intabreviewid=8531
Please note that the expected band size in these conditions is between 200 and 250 kDa.
I hope this information will be useful, but if you have any further questions or need anything else, please let me know and I'll be happy to help. I apologize for any confusion regarding the information on our datasheet, and I will see if we can update the Western blot application information.

Answer

Merci de votre réponse. La recette pour le TBS 10x est la suivante : 24.23 g Trizma HCl 80.06 g NaCl Mix in 800 ml ultra pure water. pH to 7.6 with pure HCl. Top up to 1 L. Ceci doit être dilué 10x pour obtenir du TBS 1x. Veuillez trouver les composition de différents tampons aussi sous le lien suivant: https://www.abcam.com/ps/pdf/protocols/Buffers%20and%20stock%20solutions.pdf J'espère que ce protocole va permettre d'observer un beau signal. Je me réjouis de recevoir de vos nouvelles. En attendant, n'hésitez pas à nous recontacter si vous avez des autres questions.
