Mouse pcsk9 elisa kit

Manufactured by R&D Systems
Sourced in United States

The Mouse PCSK9 ELISA kit is a quantitative sandwich enzyme-linked immunosorbent assay (ELISA) designed for the measurement of mouse PCSK9 (Proprotein Convertase Subtilisin/Kexin Type 9) levels in biological samples. This kit utilizes a specific antibody coated on a microplate to capture PCSK9 from the samples, and a second antibody conjugated with an enzyme for detection.

Plasma PCSK9 level was tested by a mouse PCSK9 ELISA kit (R&D Systems) by comparing experimental sera samples to an internal standard curve according to manufacturer’s protocol. PCSK9 level was quantified both before and after removal of immunoglobulin using Protein G-coated magnetic beads (Life Technologies). Plasma samples were incubated for 10 min with magnetic Protein G beads at room temperature. The Protein G beads were isolated using a magnet, and the immunoglobin-free supernatant was then used directly in PCSK9 ELISA kit.

In Vivo CRISPR-Cas12a Delivery and Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
C57BL/6 male mice (5 to 6 weeks) were intravenously injected with the assemblies. The mice were divided into three groups (n = 5): PBS, Cas12a/crRNA-control/NC-control/PEI/Gal-PEI-DM, and Cas12a/crRNA-exon3/NC-exon3/PEI/Gal-PEI-DM. Each mouse was injected with assemblies containing 50 μg of Cas12a (~2.5 mg/kg mouse) every other day (days 1, 3, and 5) for three times. The mice were fed under normal conditions for another week until the extraction of tissue and blood samples (day 12). After overnight fasting (day 13), the mice were euthanized for liver and peripheral blood collection. From the serum samples, PCSK9 levels were determined using the Mouse PCSK9 ELISA Kit (R&D Systems). Serum cholesterol, ALT, and albumin levels were tested at the UNC Histopathology and Laboratory Medicine. Genomic DNA of the collected livers was extracted for T7EI assay and deep sequencing. Other major organs of the mice were also harvested for H&E staining to assess potential pathological abnormalities.

PCSK9 Quantification in Plasma

Check if the same lab product or an alternative is used in the 5 most similar protocols
Plasma PCSK9 levels were quantitated by a mouse PCSK9 ELISA kit (R&D Systems) by comparing experimental sera samples diluted 200-fold to an internal standard curve. PCSK9 was quantified in this way both before and after removal of immunoglobulin using Protein G-coated magnetic beads (Life Technologies). Briefly, plasma samples diluted 1:200 were split into equivalent volumes, then either a) incubated for 10 minutes with magnetic Protein G beads or b) set aside at room temperature. The Protein G beads were isolated using a magnet, and the Ig-cleared supernatant was then used directly in the PCSK9 ELISA kit, alongside the untreated plasma sample.

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.
