Newly Launched ULTRA ELISA Kits


"Dia.Pro's new kit HTLV I&II Ab ULTRA was designed specifically to obtain the performances of the best HTLV kits on the market.

This is not simply a restyling of the previous Dia.Pro kit, but it is totally renewed in the reagents and protocol.

During the R&D of this specific product, our specialists spent a lot of time on improving the quality of the raw material peptides recombinant antigen & conjugates currently being used in the reagents.



DIA.PRO has just recently developed an ULTRA version for the Syphilis Ab kit.

Some interesting NEW specs:


Enzyme ImmunoAssay (ELISA) for the qualitative determination of antibodies (IgG, IgM and IgA) to Treponema Pallidum in human plasma and sera.

Microplates are coated with purified Treponema pallidum synthetic antigens.The solid phase is first treated with the sample and anti Tp Ab are captured, if present, by the antigens coated on the microplate.

After washing out all the other components of the sample, in the second incubation bound anti Tp total antibodies, are detected by the addition of Tp synthetic antigens, labeled with peroxidase (HRP).

The version ULTRA is particularly suitable for automated screenings.

100 ul whole sample NOT DILUTED

45’+45’+15’ (60’+60’+30’ for special use)

WITHOUT Assay Diluent (all the other components are maintained)

The conjugate is Tp synthetic antigens, labeled with peroxidase (HRP) NC mean OD450nm + 0.200

The product SIABULTRA.CE shows an analytical sensitivity better than 0.0025 IU/ml (WHO).
