Reference rhesus monomeric IgA Anti-HIV [PGT121MRA]

Reference rhesus monomeric IgA Anti-HIV [PGT121MRA]
Product Type: Reagents for IgA Detection
Format: Anti-HIV Env, PGT121, human variable region, rhesus IgA IGHA04 Fc Lambda
Clone ID: [PGT121MRA]
RRID: AB_3678714
Common Names: Reference rhesus monomeric IgA anti-HIV [PGT121MRA] | Monomeric rhesus IgA standard | CAT-00428
Target: HIV
Reactivity:
Applications: in vitro in vitro; ELISA in vitro; reference
Description:

Overview:

Rrecombinant rhesus monomeric IgA, designed as a reference standard for quantifying anti-IgA responses in nonhuman primate studies. This reagent features the PGT121-derived antigen-binding domain, ensuring HIV-specific recognition. It replaces the former reference reagent based on the b12 clone, providing an updated and more relevant standard for IgA immune response assessments.

 

Key Features:

• Monomeric rhesus IgA [MRA] Format: Recombinantly expressed as a fully assembled rhesus IgA monomer, structurally representative of circulating IgA.

• HIV-Specific Targeting: Incorporates the PGT121-derived antigen-binding domain, maintaining HIV-binding specificity.

• Optimized for Immune Response Quantitation: Developed for use in assays measuring anti-IgA responses, particularly in vaccine and therapeutic antibody studies.

 •  Closest Identity to Rhesus IGHA*04 Allele: Engineered matching the rhesus IGHA*04 allele (AY039248 / Strain RWy2.1).

•  Updated Reference Standard: Replaces the former b12-based IgA reagent, ensuring a more relevant tool for evaluating IgA-targeted immunity in rhesus macaques.

Also Available in a Dimeric Form: For studies requiring a dimeric IgA format, see CAT-00429: Rhesus Dimeric IgA aHIV [PGT121DRA].
