Keratin 5 Polyclonal Chicken Antibody, Purified

Product Details

Product Information

Intended Use:

In Vitro Diagnostic (IVD). Use in immunohistochemistry (IHC) test methods only.

The polyclonal antibody Poly9059 is used for the in vitro examination of paraffin-embedded human skin tissue sections using immunohistochemistry (IHC) methods for the qualitative identification of Keratin 5. The clinical interpretation of any staining or its absence should be complemented by morphological studies and proper controls and should be evaluated within the context of the patient's clinical history and other diagnostic tests by a qualified pathologist.

Reactivity

Human

Immunogen

This polyclonal antibody was raised against a peptide sequence derived from the C-terminus of the mouse keratin 5 protein.

Formulation

Phosphate-buffered solution + 0.1% sodium azide.

Preparation

The antibody was purified by IgY affinity chromatography.

Concentration

1.0 mg/mL

Storage & Handling

Store at -20°C. Upon initial thawing, apportion into working aliquots and store at -20°C. Avoid repeated freeze-thaw cycles to prevent denaturing the antibody. For long-term storage, keep the antibody at -80°C.

Recommended Usage

Each lot of this antibody is quality control tested by immunohistochemical staining of formalin-fixed paraffin-embedded sections of human skin.

The optimal working dilution should be determined for each specific assay condition.
• IHC: 1:200 -1:1,000 with a biotin based detection system such as biotinylated anti-chicken immunoglobulin and USA Ultra Streptavidin Detection (Cat. No. 929501).

Positive Control tissue: Human skin

Tissue Sections: Paraffin-embedded tissues
Pretreatment: For optimal staining, the sections should be pretreated with an antigen unmasking solution such as Sodium Citrate H.I.E.R Retrieval solution (Cat. No. 928502).
Incubation: 60 minutes at room temperature
