Protein concentrations of previously published candidate biomarkers were measured by ELISA. YKL-40 (Sunred Biological Technology Co) and Fetuin-A (α2-Heremans-Schmid glycoprotein, R&D systems) measurements were performed according to manufacturer’s instructions. Haptoglobin concentrations were determined by standard immunonefolometry, using a immage 800 immunochemistry system (Beckman Coulter Inc.). Thrombocyte counts were measured on a CD4000 impedance hematology analyzer.

Characterization of Stable CHO Cell Pools

Check if the same lab product or an alternative is used in the 5 most similar protocols
The stably transfected CHO cell pools expressing different targeting vectors were generated via RMCE (Fig. 1A). They were characterized for growth and titre in 14-day fed-batch cultures in 50 tubespins (TPP) in the humidified Kuhner shaker (Adolf Kühner AG). Cell density, viability and antibody titre were monitored at day 3, 5, 7, 9, 11 and 14 using the Vi-Cell XR viability analyzer (Beckman Coulter) and IMMAGE 800 immunochemistry system (Beckman Coulter), respectively. The detailed protocols for generation and characterization of stable pools were described in Supplementary Materials.

Diabetic Rat Urine and Blood Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Before BOLD-MRI, rats from the randomly chosen DM group were placed in metabolic cages for 24 h to collect 24-h urine samples. The urine albumin concentration was determined using a Beckman Coulter IMMAGE® 800 Immunochemistry system and associated reagents (Beckman Coulter, Brea, CA, USA) according to the manufacturer’s instructions, and then multiplied by 24 h urine volume to get 24 h urinary albumin excretion. Blood creatinine and urea nitrogen were tested from tail vein blood samples using a Beckman Coulter AU5800 Clinical Chemistry System (Beckman Coulter) according to the manufacturer’s instructions, and this group was euthanized for histopathological examination, as previously stated.

Immunoglobulin Levels in Ankylosing Spondylitis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Sera from all studied subjects were collected on the day when phenotypical studies were done, and stored at −80°C. Concentrations of IgG, IgA and IgM were subsequently examined in sera of AS/nb, AS/b patients and HC by nephelometry in an Immage 800 Immunochemistry System (Beckman Coulter, Brea, CA, U.S.A). For AS/b patients, determinations of Igs were also performed in serum that had been collected just before initiation of treatment with TNF blockers.

Serum Beta-2-Microglobulin Quantification in MM

Check if the same lab product or an alternative is used in the 5 most similar protocols
Serum samples of treated MM patients were taken after a 12–14 h overnight fasting simultaneously with the PB and BM samples obtained for flow cytometric analysis. Serum beta2-microglobulin (B2-M) was measured using latex particle-enhanced turbidimetry kit (Dako Beta-2-Microglobulin PET Kit, Code No. 0052) on the IMMAGE 800 Immunochemistry System (Beckman Coulter, USA).

Serum levels of immunoglobulin G, A, and M and C-reactive protein (in g/L) were assessed by automated nephelometry using an Immage 800 Immunochemistry System (Beckman Coulter). Serum autoantibodies, ANCA, RF and anti-cardiolipin were detected using the ANA test (BioRad, Philadelphia, PA), ANCA test (Inova Diagnostics, San Diego, CA), and ACA test (Orgentec Diagnostic, Mainz, Germany), respectively. Lymphocyte subsets were enumerated by flow cytometry using FACS CANTO II (BD Bioscience, Franklin Lakes, NJ) and were subsequently analyzed using FlowJo software (Tree Star, Ashland, OR, USA). Monoclonal antibodies against CD3, CD4, CD8, CD16, CD19 and HLA-DR were purchased from BD Biosciences.

Quantitative A1AT Analysis via Nephelometry

Check if the same lab product or an alternative is used in the 5 most similar protocols
The A1AT quantitative analysis was performed using an immune nephelometric method (Immage 800 Immunochemistry System, Beckman-Coulter, USA) with commercially available reagents containing goat anti-human A1AT antibody (Beckamn-Coulter, USA). The nephelometer automatically dilutes analysed samples 1:216 to achieve optimal antigen-antibody equilibrium in the assay. The normal range of the instrument for A1AT in serum samples is 88–174 mg/dL with a cutoff value of 120 mg/dL [19 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
