General notes
Ab228856 is the carrier-free version of ab209775. This format is designed for use in antibody labeling, including fluorochromes, metal isotopes, oligonucleotides, enzymes.
Our carrier-free formats are supplied in a buffer free of BSA, sodium azide and glycerol for higher conjugation efficiency.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
ab228856 is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm.

Our Abpromise guarantee covers the use of ab228856 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application | Abreviews | Notes |
---|---|---|
WB | Use at an assay dependent concentration. Detects a band of approximately 35 kDa (predicted molecular weight: 27 kDa). | |
IHC-P | Use at an assay dependent concentration. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol. |
Target

Function
Identifies cytotoxic/suppressor T-cells that interact with MHC class I bearing targets. CD8 is thought to play a role in the process of T-cell mediated killing. CD8 alpha chains binds to class I MHC molecules alpha-3 domains. -
Involvement in disease
Defects in CD8A are a cause of familial CD8 deficiency (CD8 deficiency) [MIM:608957]. Familial CD8 deficiency is a novel autosomal recessive immunologic defect characterized by absence of CD8+ cells, leading to recurrent bacterial infections. -
Sequence similarities
Contains 1 Ig-like V-type (immunoglobulin-like) domain. -
Post-translational
modificationsAll of the five most carboxyl-terminal cysteines form inter-chain disulfide bonds in dimers and higher multimers, while the four N-terminal cysteines do not. -
Cellular localization

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CD8 alpha antibody [EPR20305] - BSA and Azide free (ab228856)
This IHC data was generated using the same anti-CD8 alpha antibody clone, EPR20305, in a different buffer formulation (cat# ab209775).
Immunohistochemical analysis of paraffin-embedded mouse thymus tissue labeling CD8 alpha with ab209775 at 1/2000 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) ready to use. Membranous staining on mouse thymus. Counter stained with Hematoxylin.
Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) ready to use.
Heat mediated antigen retrieval was performed with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
