Spliceostatin A Spliceostatin A is a potent splicing inhibitor. Spliceostatin A (SSA) causes cell cycle arrest at G1 and G2/M phases. Spliceostatin A treatment inhibits mitotic clonal expansion and adipogenesis. Spliceostatin A interaction with SF3B limits U1 snRNP availability and causes premature cleavage and polyadenylation. Spliceostatin A binds to the SF3B subcomplex of the U2 small nuclear ribonucleoprotein particle (snRNP), limits U1 snRNP availability in splicing, resulting in premature cleavage and polyadenylation of MALAT1, a nuclear lncRNA, as well as protein-coding mRNAs. Therefore, truncated transcripts are exported into the cytoplasm and translated, resulting in aberrant protein products. Uses: Designed for use in research and industrial production.

SpoIVB peptidase This enzyme plays a central role in a regulatory checkpoint (the σK checkpoint), which coordinates gene expression during the later stages of spore formation in Bacillus subtilis. The enzyme activates proteolytic processing of a sporulation-specific sigma factor, pro-σK, to its mature and active form, σK, by self-cleavage. The enzyme is also subject to secondary proteolysis, which presumably inactivates SpoIVB. The enzyme is also essential for the formation of heat-resistant spores. Belongs in peptidase family S55. Group: Enzymes. Synonyms: sporulation factor IV B protease. Enzyme Commission Number: EC 3.4.21.116. CAS No. 296241-18-4. Storage: Store it at +4 ?C for short term.

Sponge microneedle powder Due to the particularity of its growth environment, Freshwater sponges gradually evolved the special bone, thats spongilla spicules. which is a siliceous spicules, very small, but has a stronger hardness, for supporting the sponge body and resisting the enemy's invasion. Spongilla spicules constituted by hard protein and heteronuclear hard protein, do not dissolve in any kind of organic solution, therefore, can be used as a kind of ideal natural materials in cosmetics and skin peeling. Freshwater sponges,usually attached to grow on the branches and corrupt leaves, the floating beings in the water and some parasitic algae, they will be salvaged with freshwater sponges together. But only the spongilla spicules are really will be used by. Other impurities are not beneficial to the skin, even cause skin allergies and infection. Therefore, we need to remove other impurities, as much as possible to extract pure spongilla spicules. The purity of our company sponge spicules extract is 99%.

spore photoproduct lyase This enzyme is a member of the 'AdoMet radical' (radical SAM) family. The enzyme binds a [4Fe-4S] cluster. The cluster is coordinated by 3 cysteines and an exchangeable SAM molecule. The 5'-deoxy-adenosine radical formed after electron transfer from the [4Fe-4S] cluster to the S-adenosyl-L-methionine, initiates the repair by abstracting the C-6 hydrogen of the spore photoproduct lesion. During the second part of the repair process the SAM molecule is regenerated. Group: Enzymes. Synonyms: SAM; SP lyase; SPL; SplB; SplG. Enzyme Commission Number: EC 4.1.99.14. CAS No. 37290-70-3. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder.
