RI-STAD-2	PKA	Cardiovascular Disease Cancer
RI-STAD-2 is a high-affinity interfering peptide that regulates the subunit RI of protein kinase A (PKA). RI-STAD-2 interferes with the binding of AKAPs and PKA-RI by simulating the interaction between AKAPs' α-helix domain and PKA-RI's dimerization/anchoration (D/D) domain, thereby affecting PKA activity and intracellular localization. RI-STAD-2 can be used to study the role of AKAPs interaction with PKA-RI in pathological processes such as cardiovascular disease and cancer .

MM-111	EGFR	Cancer
MM-111 is a bispecific antibody fusion protein targeting the ErbB2/ErbB3 oncogenic unit. MM-111 blocks activation of the PI3K pro-survival pathway. MM-111 binds to the ErbB2 receptor, which localizes the bispecific molecule to ErbB2 over-expressing tumor cells and promotes binding of the anti-ErbB3 arm to the ErbB3 receptor. MM-111 binding to ErbB3 results in inhibition of ErbB3 signaling by blocking the binding of the ErbB3 physiological ligand heregulin. MM-111 can be used for the study of ErbB2 over-expressing breast tumors .

HY-113037AS

Farnesyl pyrophosphate-d6
Farnesyl pyrophosphate-d₆ (Farnesyl diphosphate-d₆) is a deuterium labeled Farnesyl pyrophosphate (HY-113037B). Farnesyl pyrophosphate is a key isoprenoid metabolite in the mevalonic acid (MVA) metabolic pathway. Farnesyl pyrophosphate is essential for proper localization and activation of proteins .

RNA Aptamer Broccoli sodium		Aptamers
RNA Aptamer Broccoli (sodium) is a 49-nt-long aptamer that is substantially shorter than Spinach and Spinach2 and exhibits bright green fluorescence upon binding DFHBI or DFHBI-1T (soluble analogs of the fluorophore of green fluorescent protein). RNA Aptamer Broccoli (sodium) can be used to visualize RNA expression or localization in live cells. In vitro Broccoli exhibits a similar high folding efficiency as Spinach2, but exhibits markedly lower dependence on magnesium for folding and increased thermostability. Additionally, unlike Spinach2, Broccoli does not require the use of a tRNA scaffold to promote its folding in vivo.

Cas9 mRNA (5moU)		mRNA
Cas9 mRNA (5moU) expresses a version of the Streptococcus pyogenes SF370 Cas9 protein (CRISPR Associated Protein 9). Cas9 functions as part of the CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) genome editing system. In the CRISPR system, an RNA guide sequence targets the site of interest, and the Cas9 protein is employed to perform double-stranded DNA cleavage.Cas9 mRNA encodes the Cas9 protein with an N and C terminal nuclear localization signal (NLS). The incorporation of two NLS signals within the mRNA increases the frequency of delivery to the nucleus, thus increasing the rate of DNA cleavage. Additionally, a C terminal HA epitope tag aids detection, isolation, and purification of the Cas9 protein.

HY-174499

Cas9 Nickase mRNA (5moU)		mRNA
Cas9 Nickase mRNA expresses a version of the Streptococcus pyogenes SF370 Cas9 protein (CRISPR Associated Protein 9) that contains a D10A amino acid substitution. This mRNA also contains a C-terminal nuclear localization signal followed by a HA tag.Cas9 functions as part of the CRISPR (clustered regularly interspaced short palindromic repeats) genome editing system. In the CRISPR system, an RNA guide sequence targets the site of interest and the Cas9 protein is employed to perform the DNA cleavage. While wild-type Cas9 creates a double-stranded break at the target site, Cas9 nickase creates a single-stranded break. This favors homology-directed repair and decreases the occurrence of non-homologous end joining.

RNA Aptamer Corn sodium		Aptamers
RNA Aptamer Corn (sodium) is a 28-nt-long aptamer that is substantially shorter than Spinach and Spinach2 and exhibits bright red fluorescence upon binding DFHO (a soluble analog of the intrinsic fluorophore of red fluorescent protein), RNA Aptamer Corn (sodium) can be used to visualize RNA expression or localization in live cells which have been soaked with chromophores. The Corn-DFHO does not become appreciably cytotoxic when illuminated. And most importantly, Corn-DFHO exhibits markedly increased photostability compared to other aptamer-chromophore complexes both in vitro and in vivo. (36 nt Corn construct: 5'-GGCGCGAGGAAGGAGGUCUGAGGAGGUCACUGCGCC-3'; A 36-nt RNA construct, comprised of the 28-nt minimal Corn sequence extended proximally with a 4 base-pair stem.)
