Background of COL4A1-COL4A6
Collagens are highly conserved throughout evolution and are characterized by an uninterrupted ''Glycine-X-Y'' triplet repeat that is a necessary part of the triple helical structure. For these reasons, it is often extremely difficult to generate antibodies with specificities to collagens. The development of ‘type’ specific antibodies is dependent on NON-DENATURED three-dimensional epitopes. Boster extensively purifies collagens for immunization from human and bovine placenta and cartilage by limited pepsin digestion and selective salt precipitation. This preparation results in a native conformation of the protein. Antibodies are isolated from rabbit antiserum and are extensively cross-adsorbed by immunoaffinity purification to produce 'type' specific antibodies. Greatly diminished reactivity and selectivity of these antibodies will result if denaturing and reducing conditions are used for SDS-PAGE and immunoblotting.
Antibody Validation
Boster validates all antibodies on WB, IHC, ICC, Immunofluorescence, and ELISA with known positive control and negative samples to ensure specificity and high affinity, including thorough antibody incubations.

Boster anti collagen IV antibody (600-401-106 Lot 25440, 1:400, 45 min RT) showed strong staining in FFPE sections of human kidney (Left) with strong red staining observed in glomeruli; and liver (Right) with strong staining in sinusoids. Staining for both tissues was consistent with a basement membrane distribution. Slides were steamed in 0.01 M sodium citrate buffer, pH 6.0 at 99-100°C - 20 minutes for antigen retrieval.

4 Customer Q&As for Anti-Collagen Type IV COL4A1 Antibody
Question
We were well pleased with the WB result of your anti-Collagen Type IV antibody. However we have seen positive staining in placenta secreted using this antibody. Is that expected? Could you tell me where is COL4A1 supposed to be expressed?

Answer
According to literature, placenta does express COL4A1. Generally COL4A1 expresses in secreted, extracellular space, extracellular. Regarding which tissues have COL4A1 expression, here are a few articles citing expression in various tissues:

Question
We are currently using anti-Collagen Type IV antibody A01411 for human tissue, and we are happy with the IHC results. The species of reactivity given in the datasheet says human. Is it true that the antibody can work on zebrafish tissues as well?
Verified Customer

Asked: 2019-07-02
Answer
The anti-Collagen Type IV antibody (A01411) has not been validated for cross reactivity specifically with zebrafish tissues, but there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in zebrafish you can get your next antibody for free. Please contact me if I can help you with anything.

Question
We have been able to see staining in human placenta. What should we do? Is anti-Collagen Type IV antibody supposed to stain placenta positively?

Answer
From what I have seen in literature placenta does express COL4A1. From what I have seen in Uniprot.org, COL4A1 is expressed in visceral pleura, brain, placenta, among other tissues. Regarding which tissues have COL4A1 expression, here are a few articles citing expression in various tissues:
Brain, Pubmed ID: 15489334
