Alternative in vitro!
Please note that MAb 24C5 is also available as in vitro produced product under Cat.# 4BNP2cc. For immunoassays utilizing this MAb, we recommend selecting the in vitro produced product.






24C5, 26E2, 50E1, 50B7, 57H3

Hybridoma clones have been derived from hybridization of Sp2/0 myeloma cells with spleen cells of Balb/c mice immunized with human synthetic BNP (whole molecule) or synthetic BNP peptide 11FGRKMDRISSSS22 (for MAbs 24C5 and 26E2) conjugated with carrier protein.


Human BNP and proBNP.

MAb isotypes:

IgG1 for MAbs 24C5, 50E1, 26E2.
IgG2a for MAbsᅠ 57H3, 50B7


BNP and proBNP immunoassay. All MAbs recognize BNP and proBNP in sandwich immunoassay.

MAbs 24C5, 26E2, 50E1, 50B7 and 57H3 react with proBNP and BNP in Western blotting.

Recommended pairs for BNP sandwich immunoassay (capture-detection): 50E1 – 24C5, 50E1 – 26E2, 24C5 – 50B7, 24C5 – 57H3.

Sensitivity of the pair 50E1 – 24C5 is better than 1 pg/ml (synthetic BNP, Bachem). All pairs recognize with high sensitivity the antigen in plasma samples of patients with heart failure.

MAb 50E1 can be used for proBNP detection in pairs with anti-NTproBNP MAbs 16F3 or 18H5 (Cat.# 4NT1).
