COL1A1 Antibody (3G3) is a mouse monoclonal IgG3 kappa light chain antibody that targets Collagen α1 Type I, also known as COL1A1 or type I collagen alpha-1 chain, a vital component of the extracellular matrix (ECM) in various connective tissues. COL1A1 monoclonal antibody (3G3) is raised against a recombinant protein corresponding to amino acids 1021-1108 of human COL1A1, detecting COL1A1 in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and enzyme-linked immunosorbent assay (ELISA). COL1A1 is predominantly located in the ECM, where it forms fibrillar structures that provide tensile strength and structural integrity to tissues like tendons, skin, and bone. The presence of COL1A1 in the ECM is essential for maintaining tissue architecture, facilitating cell adhesion, and supporting cellular functions such as migration and differentiation. Additionally, COL1A1 plays a significant role in wound healing and tissue repair by contributing to the formation of scar tissue. Anti-COL1A1 antibody (3G3) is available in a non-conjugated form, allowing researchers to incorporate it into various experimental protocols aimed at studying collagen-related processes. COL1A1 monoclonal antibody (3G3) is recommended for researchers studying extracellular matrix dynamics and their implications in health and disease.

Do you recommend use milk or BSA with this antibody?

Asked by: MDias
Thank you for your question. This antibody has been established with UltraCruz® Blocking Reagent: sc-516214. BSA-TBST or milk-TBST are also suitable for blocking. Depending on your particular experimental setup you may want to opt for a BSA-based blocking buffer to increase overall signal strength or a milk-based buffer for improved signal to noise ratio and lower background.

Is it possible to use this antibody for IHC(P) on rabbit tissue?

Asked by: XuMY
Thank you for your question. It doesn't seem COL1A1 is fully characterized in Oryctolagus cuniculus. However, there seems to be a high homology between the epitope sequence of the antibody and the predicted sequence of collagen alpha-1(I) chain of rabbit origin, accession# XP_017204320. It may be possible that this antibody may detect your target but we cannot guarantee it since the sequence has not been fully characterized.

Would this antibody work on COL1 of porcine origin?

Asked by: KaraThrace
Thank you for your question. This antibody has not yet been tested in porcine and so that is not a recommended species at this time. We are continuously gathering data to show on our website. Check back for potential updates! If you have any further questions, please contact Technical Service.

Would this ABY work for western analysis of the purified rat-tail collagen used for cell culture?

Asked by: Monger
Thank you for your question. We haven't tested this antibody using purified rat-tail collagen used for cell culture, so we do not know if it would work on that protein.

I checked col1a1 in mice kidney extract through WB.While Band positions were detected from 52 kDa to 76 kDa, not in the same location as the protocol. Even if it is a decomposed product, the molecular weight is small. Please tell me What is it.

hello. I have an one question about this antibody. Can this antibody even recognize pro collagen type 1? I'm wondering if this ab can distinguish collagen fiber and pro collagen.

Asked by: finalb2
Thank you for your question. Based on the epitope mapping, this antibody should be able to recognize both pro collagen alpha1 type I, and the mature protein. We have not tested the antibody to determine if it can distinguish between collagen fiber and pro collagen, but we would recommend you review some of the product citations using this antibody for more information about how the antibody is being used.

Rated 5 out of 5 by from Very good bands in Western blottingBoth mature collagen and procollagen can be detected, although it takes some trickery to solubilize samples for collagen-specific protocol.

Rated 2 out of 5 by from Reduced visibility and aspecificity in WBI tested this antibody on NHDF human dermal fibroblasts, to evaluate the modulation of collagen under the modulators of the Wound healing process. However, in its application for western blot, using the 1:1000 dilution, the antibody highlights a non-specific around 50 kDa, the intensity of which reduces the visibility of the isoform for which this antibody should be specific. I recommend cutting the membrane properly.
