Stabilizing Agents

Stabilizing Agents are chemical compounds used to preserve the integrity and activity of biological molecules, such as proteins, enzymes, and nucleic acids, during experimental procedures.
These agents help maintain the structural and functional properties of these molecules by preventing degradation, aggregation, or denaturation.
Stabilizing Agents can be used in a variety of research applications, including purification, storage, and analysis of biomolecules, to ensure reproducible and accurate results.
Identifying the optimal Stabilizing Agent for your research protocols can be a challenging task, but tools like PubCompare.ai can help you easily compare the efficacy and performance of different agents across the literature, preprints, and patents, taking the gueswork out of your experiments and optimizing your research outcomes.

For the water-based, step-wise synthesis of polyacrylic acid-coated iron oxide nanoparticles (PAA-IONPs), three solutions were prepared; an iron salt solution [0.62 g of FeCl3. 6H2O and 0.32 g of FeCl2. 4H2O in dilute HCl solution (100 μL of 12 N HCl in 2.0 mL H2O)]; an alkaline solution [1.8 mL of 30 % NH4OH solution in 15 mL of N2 purged DI water]; and a stabilizing agent solution [820 mg of polyacrylic acid in 5 mL of DI water]. To synthesize the PAA-IONP, the iron salt solution was added to the alkaline solution under vigorous stirring. The resulting dark suspension of iron oxide nanoparticles was stirred for approximately 30 seconds before addition of the stabilizing agent solution and stirred for 1 h. The resulting suspension of PAA-IONPs was then centrifuged at 4000 rpm for 30 minutes and the supernatant was washed three times with DI water to get rid of free polyacrylic acid and other unreacted reagents using an amicon 8200 cell (Millipore ultra-filtration membrane YM – 30 k). Finally, the PAA-IONP suspension was purified using magnetic column, washed with phosphate buffer saline (pH = 7.4) and concentrated using the amicon 8200 cell system. The iron concentration and magnetic relaxation of the PAA-IONPs was determined as previously reported [Josephson et. al. Bioconjugate Chem. 1999, 10, 186–191]. The successful coating of the IONPs with PAA was confirmed by the presence of a negative zeta-potential (ζ = −48 mV) and the characteristic acid carbonyl bands on the FT-IR spectroscopic analysis of the nanoparticles (Supporting Information 1 and 5).

Cloning and protein preparation of TTL samples has been described by Prota et al. (2013) (link). In brief, chicken TTL containing a C-terminal hexahistidine tag was overexpressed in Escherichia coli BL21 (DE3) cells and purified on a HisTrap affinity column (GE Healthcare). The fractions containing TTL protein were pooled, concentrated to 5 ml using a Centriprep device (Mw cutoff 30,000; Amicon) and loaded onto a Superdex 200 16/60 column for the final purification step in 20 mM Bis-Tris propane, pH 6.5, 200 mM NaCl, 2.5 mM MgCl2, 5 mM β-mercaptoethanol, and 1% glycerol. The protein-containing fractions were collected, concentrated to ∼20 mg/ml, and frozen in aliquots in liquid nitrogen for storage.
The stathmin-like domain clone of RB3 was a gift from A. Sobel (Institut du Fer-à-Moulin, Paris, France). The protein was prepared according to Ravelli et al. (2004) (link). Bovine and pork brain tubulin was prepared according to well established protocols (Andreu, 2007 (link)). The bovine brain tubulin was purchased from the Centro de Investigaciones Biológicas (Microtubule Stabilizing Agents Group), CSIC, Madrid, Spain. Before the reconstitution of the T2R complex, tubulin was subjected to one cycle of polymerization/depolymerization (Dorleans et al., 2007 (link)). The composition of isoforms and post-translationally modified versions of brain αβ-tubulin is as follows: β-tubulin consists of 58% Tub B2, 25% Tub B3, 13% Tub B4 (Banerjee et al., 1988 (link)), out of which Tub B2 is polyglutamylated at Glu435 (Rüdiger et al., 1992 (link)), Tub B3 at Glu438 (Alexander et al., 1991 (link)), and Tub B4 at Glu434 (Mary et al., 1994 (link)). The composition of the α-tubulin pool is less well known; however, the highly homologous members of the Tub A1 family, which are the main components of the brain tubulin pool, are modified at Glu445 (Eddé et al., 1990 (link)). The C terminus of α-tubulin in brain is present as a mixture of tyrosinated tubulin, detyrosinated tubulin, Δ2-tubulin, and perhaps other modification variants that have only recently been discovered (e.g., Δ3-tubulin; Berezniuk et al., 2012 (link)). In adult brain, ∼35–50% of the total tubulin pool cannot be retyrosinated (Paturle et al., 1989 (link)), indicating that this pool is in the Δ2 form or further modified. Moreover, 15–20% of the pool is tyrosinated tubulin, and 35–40% is detyrosinated tubulin (Barra et al., 1988 (link)). Because the aim of our biochemical and biophysical experiments was to qualitatively/semi-quantitatively compare different TTL variants, and not to provide absolute quantitative numbers, the heterogeneity of our tubulin samples is not expected to affect the interpretation of the data.

Outcomes of interest were healthcare utilization and expenditures associated with a psychiatric diagnosis incurred by Medicaid-enrolled individuals with ASD. To identify these claims, all encounter-level claims associated with a psychiatric diagnosis (ICD-9 diagnosis codes 290–319) were extracted and categorized as inpatient, outpatient, or long term care. We did not require that claims be associated with a 299 diagnosis because children with ASD may receive care associated with other disorders, either because the disorders are truly co-occurring or because they have been assigned as a way of qualifying for services. Outpatient care was categorized as one of 10 service type categories: occupational/physical therapy, speech therapy, diagnostic assessment, case management, mental health/social skills/behavior modification, medication management, personal care/home health aide, day treatment/partial hospitalization, family therapy, and respite care. A full list of specific Current Procedure Terminology (CPT) codes and corresponding service type categorization developed by the study team can be found at http://www.paautism.org/tools.html. Psychotropic medication use was defined as any medication prescription in one of five major classes: anti-depressants, anti-psychotics, anti-anxiety agents, mood-stabilizing agents, or stimulants. Use of each category of mental health service use was dichotomously coded (used/not used). Expenditures were calculated using the amount paid for each Medicaid encounter claim. Total expenditures were defined as the sum of inpatient, outpatient, long term care and psychotropic medication expenditures.
Age in years was the primary independent variable. We examined age both as a continuous and categorical variable. For the latter, we divided patients into four groups (3–6, 7–11, 12–16 and 17–20 years of age). This categorization was chosen to compare expenditures of pre-school-age, school-age and transition-age children. Demographic characteristics included gender, race/ethnicity, and state of residence. Race/ethnicity was coded as white, black or African American, Hispanic, or other. Categories of Medicaid eligibility included foster care, poverty, disability and other. As ASDs often co-occur with other medical conditions (Levy et al. 2010 (link); Peacock et al. 2012 (link)); indicators of common comorbid psychiatric and neurological diagnoses were also included. They were identified using ICD-9 codes and included schizophrenia (295), bipolar disorder (296 excluding major depressive disorder (296.2 and 296.3)), depression (311, 296.2 and 296.3), anxiety disorders (300), attention deficit hyperactivity disorder (ADHD) (314), intellectual disabilities (317–319) and seizure disorders (345).
