How to use this

This construct is packaged for introduction into Z. mays. The transformation protocol covers the complete procedure for this host:

1
Prepare the expression system
This construct is packaged as a T-DNA binary vector for introduction into Z. mays. See the transformation protocol for delivery method and host preparation details.
2
Transform Corn
Introduce the construct using the method specified in the protocol. Delivery conditions are specific to Z. mays tissue competency and the construct's integration requirements.
3
Select with nptII (kanamycin resistance)
Propagate on selection medium at conditions given in the protocol. Non-transformed lines will not survive.
4
Screen and advance
Confirm integration using the primers included in the CRISPR guide designs. Advance confirmed transformants to the appropriate developmental stage to assess capsaicinoid expression.

Take it further with CRISPR

The CRISPR guide designs in this package are ready to use with Cas9 or Cpf1 for precision integration at defined genomic loci — and for disrupting competing pathway enzymes that reduce capsaicinoid yield. For site-specific insertion, pathway stacking, or multiplexed editing across corn cultivars, the guides are your starting point.

Work with Scoville Splice

This construct is a research tool. What it can become is an ingredient.

Scoville Splice works with food and beverage companies to take engineered capsaicinoid constructs from sequence to supply chain. If you’re developing a product — a sauce, a seasoning, a functional food — and you need a precise, consistent heat profile that no natural corn can deliver, that’s what we were built for. We offer custom cultivar development, strain characterization, pilot-scale grow protocols, and formulation consulting.
