Détail du produit anti-Collagen Type I anticorps

Highlights:

• High quality Collagen Type I Anticorps primaire for the detection of COL1.
• Reliable product with high standard validation data

Antigène: Collagen Type I (COL1) (Collagen, Type I (COL1))

Reactivité: Humain, Rat, Souris, Boeuf (Vache), Mammifères

Hôte: Lapin

Clonalité: Polyclonal

Conjugué: Cet anticorp Collagen Type I est non-conjugé

Application: Western Blotting (WB), ELISA, Immunohistochemistry (IHC), Immunoprecipitation (IP)

Réactivité croisée (Details): Typically negligible cross-reactivity against other types of collagens was detected by ELISA against purified standards. Some class-specific anti-collagens may be specific for three-dimensional epitopes which may result in diminished reactivity with denatured collagen or formalin-fixed, paraffin embedded tissues. This antibody reacts with most mammalian Type I collagens and has negligible cross-reactivity with Type II, III, IV, V or VI collagens. Non-specific cross-reaction of anti-collagen antibodies with other human serum proteins or non-collagen extracellular matrix proteins is negligible.

Purification: COLLAGEN I Antibody has been prepared by immunoaffinity chromatography using immobilized antigens followed by extensive cross-adsorption against other collagens, human serum proteins and non-collagen extracellular matrix proteins to remove any unwanted specificities.

Immunogène:

Immunogen: Collagen Type I from human and bovine placenta

Immunogen Type: Native Protein

Independent Validation (UP)

Validation #103813 (Unfolding Profile)

by: NanoTemper Technologies

No.: #103813

Date: 23.07.2019

Antigène: COL1

Numéro du lot: 41897

Application validée: Unfolding Profile

Contrôle positif: ABIN5596819

Conclusion:

Passed. ABIN5596819 showed T_i at 79.6°C and a clear unfolding profile with one unfolding event. This suggests that the antibody is properly folded and functional.

Validation Images

Unfolding profile of ABIN5596819. The fluorescence signal is plotted against temperature. The vertical line indicates the Ti at 79.6 °C.

Protocole

Full Protocol:

• Dilute ABIN5596819 in PBS buffer (Roth, 1058.1, lot 285231988) to get a final volume of 30µl at a concentration of 0.1µM.
• Load sample into Tycho capillary (NanoTemper Technologies, TY-C001).
• Run Tycho measurement.

Notes:

Tycho is designed to run quick and precise protein quality check experiments. Tycho uses intrinsic protein fluorescence to follow protein unfolding while running a fast thermal ramp, yielding results in 3min. A protein’s unfolding behavior is characterized by various parameters, most notably the inflection temperature (T_i). The T_i can be used to identify properly folded protein, to compare different batches, or to analyze the influence of storage/transport conditions on a protein. An absence of T_i would suggest that the protein is already unfolded and therefore most likely nonfunctional.

Notes:

• For antibody comparison an antibody test TMA was used that contained 80 normal tissues from 21 different organs and 95 neoplastic tissues from 18 different tumor types. For ABIN5596819 the staining was typically fibrillar. Positive fibrillar structures were often located adjacent to benign and malignant epithelial structures, in smooth muscles or around vessels of all sizes.

• The anti-collagen type I antibody ABIN5596819 shows a predominantly fibrillar staining pattern involving stroma components that are often located adjacent to benign and malignant epithelial structures, in smooth muscle or around vessels of all sizes. Collagen I staining is also seen in the stroma of many tumors. The staining of these fibrillar structures by ABIN5596819 is often faint at a dilution of 1:50. Staining of fibrils by ABIN5596819 is stronger at a dilution of 1:15 but in this case a significant background staining occurs in many epithelial tissues. Of note, a membranous staining of intratubular testicular cells was seen by ABIN5596819. Considering the expected staining pattern of an anti-collagen type I antibody, this may represent a cross-reactivity of ABIN5596819.

• According to the rather ubiquitous nature of collagen I expression, orthogonal validation is not optimally suited for the validation of collagen I antibodies. In agreement with RNA screening studies, including the Human Protein Atlas (HPA) RNA-seq tissue dataset, the FANTOM5 project, and the Genotype-Tissue Expression (GTEx) project (all summarized in https://www.proteinatlas.org/ENSG00000108821-COL1A1/tissue), collagen I staining by ABIN5596819 was significant in the placenta, smooth muscle, urinary bladder and the endometrium. These are the tissues with the highest recorded RNA expression among the tissues analyzed in this project.

Background: 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. Rockland 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. Ideal for investigators involved in Cell Biology, Signal Transduction and Stem Cell research.
