R&D Systems?Probe Cocktails are pre-made antisense oligonucleotide probes complementary to the cytokine and adhesion molecule sequences of interest. Typical applications include library screening, dot blots, Northern blots, Southern blots and in situ hybridization.

R&D Systems?PCR Primer Pairs have been carefully tested to identify optimum amplification conditions so you spend less time optimizing PCR. With each PCR primer pair, you receive detailed sequence information, a positive control template, and gene-specific tips to make your RT-PCR successful. Select the PCR primer pairs for the cytokines, adhesion molecules, or soluble factors that are important in your research application.

RNA Quantitation Kits available include: Cytoprime PCR Amplification Kits, Quantikine mRNA Colorimetric Kits, and an RNA Isolation Kit.
