AASTYs (Acrylic acid-co-styrenes) - like AASTY 6-50 - are highly-alternating copolymers, well-suited for the generation of native lipid nanodiscs. They are a 2022 novel developed series for membrane protein solubilization & stabilization. AASTY 6-50 gets its name from its molecular weight and Acrylic Acid : Styrene Ratio. These varying ratios of acrylic acid to styrene contribute to the hydrophilic properties of our AASTYs. In general lighter AASTYs, like 6-50 tend to be more aggressive, while heavier AASTYs, such as 11-45 show higher thermodynamic stability.

The exact composition of AASTY copolymers shows different extraction efficiency, depending on the lipid composition of the lipid bilayers being formulated into nanodiscs. As AASTY is made using controlled radical polymerization techniques, the dispersity of polymer molecular weight distribution is low, and the molecular weights are controlled. This means that excess AASTY copolymer can be removed by dialysis after nanodisc formation. Based on previous findings on SMA, it is the expectation that AASTY of different molecular weights will display different rates of nanodisc formation, extraction efficacy, and stability of resulting nanodiscs.

Every membrane protein solubilization needs to undergo a screening process before. The characteristic phospholipid environment surrounding the different membrane proteins in question performs differently well with each polymer. To support you in this process we offer a handy Screening Kit for AASTYs to test them all. Additionally, we recommend the two following publications if you would like to get further information: Smith et al. 2020 & Timcenko et al. 2022

Sulfo-DIBMA is an electroneutral modification of existing DIBMAs. It does not interfere with charge-sensitive interactions between proteins and lipids. This innovation opens up a wider range of experimental research in terms of charge-sensitive membrane protein processes like protein-protein and protein-lipid interactions. In addition, Sulfo-DIBMA belongs to a new generation of DIBMA’s which are RAFT polymerized. This achieves a reduction in both monomer size and greater monodispersity. With diisobutylene-maleic acid (DIBMA), you can directly extract membrane proteins from cells without an intermediate step of detergent solubilization, like with SDS, which would usually interfere with the protein's function. Another advantage of DIBMA is the lack of an absorbance maxima at 280 nm. SMAs, in comparison, usually interfere with protein quantification, as aromatic amino acids absorb at the same spectrum.
Another significant advantage of Sulfo polymers compared to other polymers is the wide pH range in which they remain stable. The buffer in which the polymer is supplied has a pH of 7.5, but the polymer itself remains stable between pH 4 and pH 10. The special physicochemical properties of Sulfo-DIBMAs make them ideal for cryo-TEM and other downstream applications.
Good publications to find details about Sulfo-DIBMA and Sulfo-SMA are:

Glueck et al. (2022)
Janson et al. (2022)

FAM129B, also known as Niban-like protein 1, belongs to a poorly characterized protein family with unknown category and function. Increased expression of the Niban gene has been observed in renal carcinomas. Suppression of FAM129B expression in HeLa cells has been seen to promote apoptosis, suggesting that it can modulate cell death signaling, and may be involved in the ER stress response. FAM129B is also up-regulated in various types of thyroid tumors and Hashimoto’s thyroiditis. It has been suggested that the MAP kinase dependent phosphorylation of FAM129B is important in controlling melanoma cells, as inhibition of B/Raf/MKK/ERK in melanoma cells represses invasion. It is believed that phosphorylated FAM129B not only derepresses invasion, but also regulates events that promote invasion. FAM129B pS679/683 Antibody is ideal for researchers interested in cancer research.

Fibrillarin is part of the small subunit processome complex, involved in the processing of pre-18S ribosomal RNA. Nop1p is the yeast homologue of fibrillarin. Fibrillarin/Nop1p is extraordinarily conserved, so that the yeast and human proteins are 67% identical, and the human protein can functionally replace the yeast protein. This means that suitably cross-reactive antibodies to Nop1p/fibrillarin such as this antibody can be used to reveal nucleoli and study fibrillarin/Nop1p in all eukaryotes and archea tested to date. This antibody is becoming widely used as a convenient marker for nucleoli in a wide variety of species. This antibody reacts with human, Rat, Drosophila, S. pombe, C. elegans, S. pombe.

The SK1 antibody is specific for the 32-34 kDa alpha chain of human CD8, known as CD8a or CD8 alpha. CD8a can form a homodimer (CD8 alpha-alpha), but is more commonly expressed as a heterodimer with a second chain known as CD8b or CD8 beta. CD8 acts as a co-receptor for antigen recognition and subsequent T cell activation that is initiated upon binding of the T cell receptor (TCR) to antigen-bearing MHC Class I molecules. The cytoplasmic domains of CD8 provide binding sites for the tyrosine kinase lck, facilitating intracellular signaling events that lead to T cell activation, development, and cytotoxic effector functions. CD8+ cytotoxic T cells (CTLs) play an important role in inducing cell death of tumor cells, as well as cells infected by virus, bacteria or parasites.

The CD28.2 antibody reacts with human CD28, a 44 kDa type I surface glycoprotein which acts as a co-stimulatory receptor in support of the T cell receptor (TCR). CD28 exists as a homodimer with specificity for two known ligands, known as B7-1 (CD80) and B7-2 (CD86), which are expressed on activated B cells and antigen-presenting cells. These ligands trigger CD28 signaling in concert with TCR activation to drive T cell proliferation, induce high-level expression of IL-2, impart resistance to apoptosis, and enhance T cell cytotoxicity. The interaction / co-stimulatory signaling between the B7 ligands and CD28 provides crucial communication between T cells and B cells or APCs to coordinate the adaptive immune response. Other members of the CD28 family of receptors include CTLA-4 (CD152), PD-1 (CD279), ICOS and BTLA.

The 3G3 antibody reacts with mouse Foxp3, a 50-55 kDa transcription factor which is a central regulator of T cell activity and is critical for the development and function of regulatory T cells (Tregs). Foxp3 is expressed at constitutively high levels in Treg cells, which are further identified as being CD4+ CD25+. In resting conventional T cells (CD4+ CD25-) Foxp3 expression is restricted, and upon TCR activation is expressed only transiently and in a small proportion of cells. However, the growth factor TGF-beta has been shown to induce expression of Foxp3 in naïve T cells, driving their development into Foxp3+ Tregs, which are called “induced” or “adaptive” Tregs. These cells are phenotypically similar to so-called “natural” Tregs (CD4+ CD25high Foxp3+) which originate in the thymus and comprise the majority of Treg cells. Tregs are critical for maintaining peripheral tolerance and are implicated in the development of autoimmunity.

Interleukin 6 (IL6) is a multifunctional 24 kD protein originally discovered in the medium of RNA stimulated fibroblastoid cells. It is upregulated by IL1, TNF, PDGF, IFN beta, TNF alpha, NGF, IL17 and downregulated by glucocorticoids IL4, TGF beta. IL6 appears to be directly involved in the responses that occur after infection and cellular injury, and it may prove to be as important as IL1 and TNF alpha in regulating the acute phase response. IL6 has also been implicated in regulating adipose mass. IL6 is reported to be produced by fibroblasts, activated T cells, activated monocytes or macrophages and endothelial cells. It acts upon a variety of cells including fibroblasts, myeloid progenitor cells, T cells, B cells and hepatocytes. In addition, IL6 appears to interact with IL2 in the proliferation of T lymphocytes. IL6 potentiates the proliferative effect of IL3 on multipotential hematopoietic progenitors.
