Activin/Inhibin - R&D Systems
9, 18 However, possibly due to variable proteolytic processing of the beta-subunit prosequence (called probetaA) at the surface of secreting cells, beta-precursors can also be released that form dimers with other beta-precursors or mature (betaA) forms.

Interleukin 1 - R&D Systems
4, 5, 8, 22, 23 Structural Information Human IL-1 alpha and IL-1 beta are synthesized as 31-33 kDa, variably glycosylated pro-cytokines that share 25% amino acid (aa) identity across their entire precursor structure, and 22% aa identity over their mature segments.

Bone Morphogenetic Proteins (BMPs) - R&D Systems
6, 7, 9 Cleavage of the variable length pro-segment occurs prior to secretion. The presence of N-linked glycosylation sites is variable. 74, 75 Type I Receptors ALK-1: ALK-1 (Activin-like kinase-1) is a 62-72 kDa, 503 aa type I transmembrane glycoprotein that contains a 21 aa signal sequence, a 97 aa extracellular region, a 23 aa...

Th1/Th2 - R&D Systems
9,12,60-62 Not all cytokines are equal in their effects, however, and this is in part due to variability of receptor expression. For example, TGF-beta in the presence of IL-4 and high IL-2 may drive naive T cells to a Th1 phenotype.

Methods for Detecting Protein Phosphorylation - R&D Systems
Phosphorylated JNK in IL-1 beta-treated HepG2 Cells. Normalizing the fluorescence signal derived from the phospho-protein to that of the total protein makes it easy to account for potential well-to-well variabilities such as differences in cell number.

The Toll-like Receptor Family - R&D Systems
All of the TLRs are Type I transmembrane proteins possessing a variable number of N-terminal leucine rich repeats (LRRs) followed by a cysteine rich domain, a transmembrane (TM) domain, and an intracellular Toll/IL-1 receptor (TIR) domain.

Wnt Receptors and Pathways - R&D Systems
beta-Catenin, in an active form, is a transcriptional activator for the TCF (T cell factor)/LEF-1 (lymphoid enhancer factor 1) family of DNA binding proteins. Five of the propeller blades contain an unusual and variable Tyr/Phe-Trp-Ile/Gly/Thr-Asp/Cys/Asn (YWTD) tetrapeptide in its structure.

However, these reagents can be quite toxic (particularly DEAE-dextran), are prone to variability and are not suited for in vivo gene transfer to whole animals. Note that the best results are obtained when variability is minimized among lots of serum.
