EBS-CD-007 recognized a protein of 32 kDa, identified as CD8b. The CD8 molecule consists of alpha and beta chains, which are disulphide-linked into heterodimers or homodimers. CD8 is expressed on a T-cell subset (cytotoxic-suppressor T-cells), thymocytes and NK cells. The majority of CD8+ T-cells express CD8 as a heterodimer. Some subpopulations of CD8+ T-cells as well as NK-cells may express it as a homodimer. CD8 functions as a co-receptor in concert with TCR for binding the MHC class I/peptide complex. HIV-2 envelope glycoprotein binds CD8 alpha chain, but not beta chain.
Positive control: HuT78 or hPBL, tonsil.
Q & A's
0 of 0 reviews
The concentration of purified antibodies is mentioned on the datasheet.
For prediluted antibodies the concentration may vary from lot to lot. The concentration of these antibodies is not mentioned on the datasheet and can be requested at firstname.lastname@example.org.
The supernatant format contains FCS proteins from cell culture medium supplemented with FCS.
The serum antibodies contain other proteins present in serum.
- Supernatant and supernatant concentrate: This format contains hybridoma cell culture supernatant. The antibody is not purified and the antibody concentration is not determined. The antibody concentration may vary from lot to lot. Therefore we recommend to titrate the optimal concentration for the application used for each new lot.
- Lyophilized, purified: This format contains purified antibody in lyophilized form. The reconstitution of this antibody is described in the datasheet. The buffer composition after reconstitution is also mentioned on the datasheet.
- Liquid, purified: This format contains purified antibody in liquid format. The concentration is mentioned on the datasheet.
- Prediluted, purified: This format contains purified antibody in liquid format. Most antibodies in this format are diluted to be ready-to-use for IHC with standard tissue. But some antibodies of this format need further dilution for IHC. This is mentioned on the datasheet.
Most of our liquid antibodies and reconstituted lyophilized antibodies may be stored for short term storage (up to 3 month) at 2-8°C. For long term storage we recommend to store the antibody at -20°C in aliquots. Please avoid freeze and thaw cycles.
Most of our conjugated antibodies should be stored at 2-8°C.
The individual storage conditions are mentioned on the datasheet.
