This kit includes Streptavidin-ZAP (IT-27) and Blank-Streptavidin-SAP (IT-27B).
Streptavidin-ZAP is a chemical conjugate of streptavidin and the ribosome-inactivating protein, saporin. It converts biotinylated materials into targeted toxins. Blank-Strep-SAP is the perfect control for use with peptide conjugates utilizing biotin linkage to Streptavidin-ZAP. It consists of a non-targeted peptide that has been biotinylated and mixed with Streptavidin-ZAP.
This kit converts biotinylated materials into targeted toxins and will allow you to evaluate the ability of your reagent to internalize upon binding to its receptor. It is the perfect tool to screen your biotinylated peptide in vivo.

Antibody drug conjugates targeted to CD45 or CD117 enable allogeneic hematopoietic stem cell transplantation in animal models
Palchaudhuri R, Hyzy SL, Proctor JL, Adams HL, Pearse BR, Sarma G, Aslanian S, Gillard G, Lamothe TL, Burenkova O, Brooks ML, Gabros AD, McDonagh CF, Boitano AE, Cooke MP (2018) Antibody drug conjugates targeted to CD45 or CD117 enable allogeneic hematopoietic stem cell transplantation in animal models. Blood 132:3324. doi: 10.1182/blood-2018-99-119432
Objective: To further investigate and develop the utility of CD45-SAP and CD117-SAP, in combination with immunosuppression, in murine transplant models using i.v. administration in an allogeneic minor mismatch transplant model (Balb/c donor into DBA/2 recipients).
Summary: CD45-SAP or CD117-SAP in combination with immunosuppressants (30Fll and post-transplant Cytoxan) enabled >85% peripheral donor chimerism at 12 weeks post-transplantation. CD45-SAP and CD117-SAP were more effective at conditioning versus 2Gy TBI or pretransplant Cytoxan.
Usage: CD45-SAP (1.9 mg/kg, iv) and CD117-SAP (1mg/kg, iv) in an allogeneic minor mismatch transplant model (Balb/c donor into DBA/2 recipients).

Antibody-based preparative regimens for cell, tissue and organ transplantation
Van Hentenryck M, Li Z, Murphy PM, Czechowicz A (2022) Antibody-based preparative regimens for cell, tissue and organ transplantation. (eds. 162). OBM Transplantation 6(3):162. doi: 10.21926/obm.transplant.2203162
Objective: Provide a review of progress in the use of antibodies to support cell and tissue transplantation with a particular focus on induction of donor-specific tolerance for solid organ transplantation.
Summary: Antibody-based conditioning to prepare the recipient is a promising approach towards achieving transplant tolerance in both hematopoietic and solid organ transplant settings.
Usage: To enhance HSC depletion while avoiding bystander toxicity (neutropenia, lymphopenia, and thrombocytopenia) caused by CD45-radioimmunotherapy, Palchaudhuri et al. developed a saporin-based CD45 (CD45-SAP) immunotoxin using a biotinylated antibody and Streptavidin-ZAP.

Kohls M (2006) Evaluate Potential Targeting Molecules. Nature Methods
Summary: Targeted toxins -- targeting agents conjugated to saporin -- are widely used to eliminate specific cell populations both in vitro and in vivo. For these molecules to be effective, it is vital that the targeting component of the conjugate specifically binds the cells of interest. A secondary conjugate, Streptavidin-ZAP, has been created by attaching the toxin saporin to streptavidin. The user can combine primary biotinylated material with Streptavidin-ZAP to quickly and economically screen potential targeting molecules for internalization and specificity. Once the appropriate targeting molecule is identified, a direct conjugation with saporin can be performed.
