  • Relevance
    HIV1 performs highly complex orchestrated tasks during the assembly, budding, maturation and infection stages of the viral replication cycle. During viral assembly, the proteins form membrane associations and self-associations that ultimately result in budding of an immature virion from the infected cell. Gag precursors also function during viral assembly to selectively bind and package two plus strands of genomic RNA. Capsid protein p24 probably forms the conical core of the virus that encapsulates the genomic RNA-nucleocapsid complex.

Customer reviews and Q&As

Unfortunately we are unable to share the specific sequence but it is available in the literature. The protein is derived from group MN. These regions are highly conserved throughout all strains.

Thank you for contacting us.

The immune-biological activity of HIV p24 is derived from its linear AA sequences and has no secondary structure related activity. This protein has not been tested for functional activity.

I hope...

You are correct, ab43037 is an antigen, not an antibody, and it is suitable to be coated on an ELISA plate from 100 ng to 10 ug. The dilution buffer that you use does not have to contain urea, as long as you are coating the wells within the range given...

ab43037 works well in ELISA at nano to tens of micro gram levels. Thus, dilutions within that range should work sufficiently.

Thank you for contacting us.

The laboratory provided the following ranges for ELISA. Using ab43037 protein use 100 ng to 10 ug to coat the plate, detection with ab81433 use at 1/5000-1/10000.

I hope this information is helpful to ...

I have checked some of the HIV1 p24 proteins available in our catalogue with my lab colleagues. Regarding their suitability for ELISPOT, I am afraid it hasn’t been tested in our lab, but due to their suitability in ELI...

Thank you for your reply. Unfortunately, I would not recommend the protein ab73768. This is only a fragment of the HIV1 p24 that lacks large parts of the protein such as the N-terminal amino acids (1-76). If the antibodies you would like to test re...
