This collagen antibody was developed using non-denatured 3D epitopes, you must be careful not to denature the collagen protein during your experiment. - Interrupted Electrophoresis : Interrupted gel electrophoresis was used to assess the amount of type III collagen (BBRC, 72 (4) 1472 - 80 (1976)). ELISA: Tips for Collagen Western Blotting Collagens are insoluble in organic solvents, while water-soluble collagen represents only a small fraction of total collagen. recommended for detection of Collagen α1 Type I of mouse, rat and human origin by WB, IP, IF, IHC (P) and ELISA. Type III collagen was not detected by Western blot over the 10-week period. Western blot analysis of the antibody showed that its determinant was the alpha 3 (V) chain of type V collagen. PV-9002, Polink-2 plus Polymer HRP Detection System; Zhongshan Goldenbridge Co. Ltd., Beijing, China) at 37°C for 1 h. Western blot of the mice liver tissue was also done to detect the activation of the JNK signalling pathway related to liver fibrosis. Real-time reverse-transcription polymerase chain reaction (PCR), Western Blot, and Toluidine blue staining demonstrated that apigenin stimulated type-I and type-III collagen synthesis of fibroblasts on the mRNA and protein levels. Western blotting. Category: Western Blot Reagents Furthermore, collagen 1, collagen 3 and α-SMA expression were detected by qRT-PCR and western blot. Secreted phospholipase A2 (sPLA2) is a protein secreted by Clonorchis sinensis and is a component of excretory and secretory products (CsESPs). Then, the samples were incubated overnight at 4°C with anti-collagen II antibody (as with the Western blot). IF. RNA analysis was performed by qRT-PCR and a Total Collagen Assay was utilized to evaluate collagen. with HE and Masson staining were observed for collagen accumulation. expression. Type III Collagen Western Blot : Type III collagen was detected as a minor component of the human collagen in a Western Blot assay specific for human Type III collagen. In general, the smaller the protein, the faster it migrates through the gel. Cross-reactivity with other human serum proteins and non-collagen extracellular matrix proteins is neglible.|Western blot: this preparation results in a native conformation of the protein. The blot was re-probed with anti-NMHC-IIA antibodies (lower panel). ab138492 has not been experimentally confirmed in cell lysates in western blot. After three PBS washes, the cells were immersed in polyclonal goat anti-mouse secondary antibody (cat. (e) Representative Western blot analysis of the intracellular content of collagens VII, II and I in the cells. with same sample and protocol, other . For extended storage, mix with an equal volume of glycerol, aliquot contents and freeze at -20° C or below. Call 800.722.2255 or contact us The baby had repeated episodes of respiratory distress necessitating assisted ventilation. Protein concentration was determined using the Bradford method. Tested in Western Blot (WB), Immunocytochemistry (ICC/IF), Immunohistochemistry (Frozen) (IHC (F)) and Immunohistochemistry (Paraffin) (IHC (P)) applications. Printed in USA 6/09. Western blotting experiments . with same sample and protocol, other proteins are seen well by western blotting . Indirect ELISA is not recommended because the native structure of collagen is disrupted when directly bound to the ELISA plate and therefore the specificity of the antibody may be lost. Boster Scientific Support. Further analysis of the composition of ECM-derived hydrogels was performed using SDS-PAGE and western blotting. Many procedures suggest the use of limited proteolytic digestion followed by salt extraction while maintaining the collagen preparation on ice. Western Blot (Mayne, 1994) Immunohistochemistry (Formalin/Paraffin): 1-2 μg/mL, 30 minutes at room temperature. Western blotting was used to analyze the type II collagen degradation products. Tips for collagen Western blotting Collagens are insoluble in organic solvents, and water-soluble collagen represents only a small fraction of total collagen, depending on the age and type of tissue. Western blots using antibodies against collagen α1 (II) showed an absence of collagen type II in laryngeal tissue, which may explain the laryngeal collapse and impaired respiratory functions. Indirect immunofluorescent staining of intact human skin with the antibody produced staining of the dermal blood vessels but not of the dermal-epidermal junction (DEJ). Western blot analysis of concentrated medias from various cell lines using COL1A1 Antibody. Immunofluorescence analysis showed the ability of EC-I to induce a significant increase of type I and III collagen levels, parallel with overexpression of crucial proteins in collagen biosynthesis, maturation, and secretion, prolyl 4-hydroxylase (P4H) and heat shock protein 47 (HSP47), as demonstrated by western blot experiments. laminin, fibronectin, or types I and IV collagen. High levels of type II and type X collagen gene expression were demonstrated by RT-PCR. However, migration is also affected by other factors, so the actual band size observed may differ from that predicted. To analyze the role of MMPs and TIMPs in tissue remodeling under normal and pathological conditions . Deregulation of this balance is a characteristic of extensive tissue degradation in certain degenerative diseases. Western Blotting; Application Notes: Western Blot Analysis: 1:500 dilution of a previous lot detected Collagen Type I on 10 μg of Mouse Liver lysate. 3 RESULTS . The amount of antibody supplied is sufficient for 25 Western Blots. no. However, the strain did allow collagen production The purpose of this study was to investigate the effect of Bletilla striata on postoperative intestinal adhesion in rats. - Western blotting using specific collagen antibodies - Sirius Red based staining of tissue sections - Sirius Red based assays for soluble collagen - Determination of Hydroxyproline residues (either by a colorimetric kit or by HPLC) after hydrolysis of the sample. The ECL Western Blotting Substrate detects picogram amounts of antigen, and with the use of photographic or other imaging methods, visualizes the presence of HRP. The JNK signalling pathway is involved in hepatic stellate cells (HSCs) activation. The balance between matrix metalloproteinases (MMPs) and their inhibitors, the tissue inhibitors of metalloproteinases (TIMPs), is largely responsible for the remodeling of tissues. The stabilization of type I collagen α 1(I) is mediated by the binding of the poly(rC)-binding protein 2 (αCP2, encoded by the PCBP2 gene) to the 3'-UTR regions of the type I collagen α1(I) mRNA [17, 18]. When I tried to see a down regulation of collagen type 1 by western blotting, noises are appeared always. Determination of incompatibility group plasmids. Conclusion: These studies demonstrate the production in vitro of cartilage-like tissue with similar morphological, histochemical and Bletilla striata (BS) is an important hemostatic drug used in China for nearly 2000 years. Staining of paraffin embedded tissues requires digestion of tissue sections with pepsin at 1mg/mL in Tris HCl . RIA: A 1:200 dilution of a previous lot was used in RIA. For immunoblotting, samples containing 2 μg of protein were loaded onto two 12% SDS-PAGE gels. Blots can be repeatedly exposed to X-ray film to obtain optimal results or stripped of the immunodetection reagents and reprobed. Real-time reverse-transcription polymerase chain reaction (PCR), Western Blot, and Toluidine blue staining demonstrated that apigenin stimulated type-I and type-III collagen synthesis of fibroblasts on the mRNA and protein levels.
