# Plate layouts for IDT for Illumina DNA/RNA UD Index kits, Sets A, B, C, and D
The following tables depict the plate layouts for IDT for Illumina Nextera DNA UD Indexes, IDT for Illumina DNA/RNA UD Indexes, and IDT for Illumina PCR UD Indexes, which are designed for dual-indexing.
**IDT for Illumina UD Indexes Plate A/Set 1**\
**IDT for Illumina UD Indexes Plate B/Set 2**\
**IDT for Illumina UD Indexes Plate C/Set 3**\
IDT for Illumina DNA/RNA UD Indexes and IDT for Illumina PCR UD Indexes utilize the same indexes as IDT for Illumina Nextera DNA UD Indexes except for where a v2 index is indicated.\
**IDT for Illumina UD Indexes Plate D/Set 4**\
IDT for Illumina DNA/RNA UD Indexes and IDT for Illumina PCR UD Indexes utilize the same indexes as IDT for Illumina Nextera DNA UD Indexes except for where a v2 index is indicated.\
The Index Adapters Pooling Guide, linked [here](https://support.illumina.com/downloads/index-adapters-pooling-guide-1000000041074.html), contains these tables along with recommended index combinations for low-plexity library pooling.
