Serum Protein Electrophoresis in Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
Mice blood samples were collected at time of euthanasia. Samples were allowed to coagulate at room temperature and spun at 3000 × G for 10 min; 0.5 μl of sera were loaded in precast QuickGels (Helena Laboratories, 3505T) and run on a QuickGel Chamber (Helena Laboratories, 1284) according to the manufacturer's instructions. Samples were analyzed in triplicate with M-spike positive samples visible in all three analyses.

Serum Protein Electrophoresis in Myeloma Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
Serum protein electrophoresis (SPEP) was performed to identify M-protein spikes in the WT 5TGM1-GFP and Itga4 KO 5TGM1-GFP myeloma mouse models used in this study. Blood samples were collected from the mice by cheek bleed technique in serum separating tubes. The serum was separated from samples by centrifuging at 1000 rpm for 10 min. These serum samples were analyzed on a QuickGel Chamber apparatus using pre-casted QuickGels (Helena laboratories) according to the manufacturer’s instructions. The % gamma globulin values were quantified from the bands using ImageJ software (Maryland, USA). The data is presented as mean + /− standard deviation using GraphPad Prism 8.0 (La Jolla, CA, USA).

Blood was collected from mouse tail vein, followed by centrifugation and serum collection. Assay was conducted according to the manufacturer’s protocols. Briefly, serum was diluted 5-fold in PBS before loaded on a QuickGel SPE Gel (Helena Laboratories, catalog 3505T). Electrophoresis was run at 400 V for 5 minutes. Gels were dried with a QuickGel Chamber (Helena Laboratories, catalog 1284) for 15 minutes followed by staining with Acid Blue for 2 minutes and de-staining with Destain solution for 10 minutes.

Serum Protein Analysis for Myeloma

Check if the same lab product or an alternative is used in the 5 most similar protocols
Blood was collected from mice periodically by cheek bleeding. About 100 μL of whole blood were collected into microtainer tubes (BD Biosciences), allowed to coagulate at room temperature, and spun for 10 minutes at 2,300 × g. Sera were diluted 1:2 in normal saline buffer and analyzed on a QuickGel Chamber apparatus using pre-casted QuickGels (Helena Laboratories) according to the manufacturer’s instruction. Densitometric analysis was then performed using the clinically certified Helena QuickScan 2000 workstation which allows a precise quantization of the various serum fractions, including the measurements of gamma/albumin (G/A) ratio. A G/A ratio between 0.5–2.0 corresponds to predominant M-spikes and suggest not only good multiple myeloma engraftment but also tumor response to treatments in similar factions as is done clinically [10 (link)].

A KaLwRij myeloma mouse model was used as described (32 (link)). KaLwRij mice were inoculated intravenously with 1 × 106 5TGM1 cells and distributed into six groups of 6 to 8 mice, and treated intravenously (a) nontargeted (NT) or targeted (T), (b) drug-bearing (D) or no-drug (ND) PFC or micelle NPs. The following treatment cohorts were studied: (i) ND/NT 200 nm PFC NP; (ii) T/ND 200 nm PFC NP; (iii) T/D 200 nm PFC NP; (iv) NT/ND 20 nm micelles; (v) T/ND 20 nm micelles, and (vi) T/D 20 nm micelles. 5TGM1 cells were injected via tail vein on day 0. NPs were administered by tail vein injection on days 3, 5, 7, 10, 12, and 14 with 50 μL of MI1 (0.145 mg/mL) per mouse. Sera were collected on day 17, diluted 1:2 in PBS, and analyzed by serum protein electrophoresis (SPEP) on a QuickGel Chamber apparatus using precasted QuickGels (Helena Laboratories) according to the manufacturer's instruction. Densitometric analysis of the SPEP traces was performed using the clinically certified Helena QuickScan 2000 workstation, allowing a precise quantification of the various serum fractions, including the measurements of gamma/albumin ratio.

Comprehensive Blood Analysis Protocol

A complete blood count (CBC) was determined using the Advia 120 Hematology System (Siemens Healthineers, Erlangen, Germany). To measure total serum IgG, blood was collected into Eppendorf tubes, allowed to coagulate at room temperature for 5 minutes, and centrifuged for 10 minutes at 850 g. Total IgG in serum was then determined by ELISA using the Easy- TiterMouse IgG Assay Kit and Mouse IgG Isotype Control (Thermo Fisher Scientific, Rockford, IL) according to the manufacturer’s protocol. For serum protein electrophoresis, sera were diluted 1:2 in normal saline buffer and then analyzed on a QuickGel Chamber apparatus using Precasted QuickGels (Helena Laboratories, Beaumont, TX) according to the manufacturer’s instructions.

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.
