Pro-Collagen I Antibody Staining Protocol for Immunohistochemistry


Description: Suitable for formaldehyde/formalin fixed paraffin sections as well as fresh frozen tissue sections. Does not stain mature collagen fibers in tissue. Localized intracellularly in cells producing pro-collagen I.


Primary Antibody

Name: Pro-Collagen I Amino-Terminal Antibody

Clone: M-58, Rat anti-Human

Supplier: Chemicon

Catalog Number: MAB1912

Dilution: 1:500 for paraffin sections, 1:10,000 for frozen sections using IHC-TekTM Antibody Diluent (Cat# IW-1000 or IW-1001) to reduce background and unspecific staining and serum blocking step is NOT needed.

Incubation Time/Temp: 60 min/room temperature

Antigen Retrieval
Device: Incubator
Buffer/pH value: IHC-TekTM Proteinase K Solution (Cat# IW-1101)
Heat/Cool Temperature: 37 ºC/room temperature
Heat/Cool Time: 20 minutes/20 minutes

Detection Methods
Standard Method: ABC Method or LSAB Method
Enhanced Method: Polymeric Methods

Chromogen Substrate
Reagent: DAB
Incubation Time/Temperature: 1-3 minutes/room temperature

Reagent: Mayer's Hematoxylin
Staining Time: 30 seconds

Staining Pattern: Collagen fibers
Images: Search image

Additional Information:
Species Reactivity: Human
Fixation: Formalin fixed paraffin sections, or acetone fixed frozen sections (no antigen retrieval needed)
Positive Control: Human skin
Negative Control: Omit primary antibody, isotype control, absorption control
Blocking: 2-5% normal serum to reduce unspecific background staining; 0.5-3% H2O2 to block endogenous peroxidase activity; avidin/biotin to block endogenous biotin activity if necessary
