Specificity

Natural and recombinant human ANGPTL3

Product Summary

The Quantikine Human ANGPTL3 Immunoassay is a 3.5 hour solid-phase ELISA designed to measure human ANGPTL3 in cell culture supernates, serum, and plasma. It contains Sf 21-expressed recombinant human ANGPTL3 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human ANGPTL3 showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human ANGPTL3.

Background: Angiopoietin-like Protein 3/ANGPTL3

Angiopoietin-like, also known as angiopoietin-related proteins, are structurally related to the angiopoietins. They are secreted proteins with N-terminal coiled-coil domains and C-terminal fibrinogen-like domains. Unlike the angiopoietins, ANGPTLs do not bind Tie-2. Seven ANGPTL proteins have been identified (ANGPTL1 through 7).

Long   Name:

Angiopoietin-5

Entrez   Gene IDs:

27329   (Human); 30924 (Mouse); 102136264 (Cynomolgus Monkey)

Alternate   Names:

AGNPT5;   Ang-5; angiopoietin 5; Angiopoietin-5; angiopoietin-like 3; Angiopoietin-like   Protein 3; angiopoietin-related protein 3; ANGPT5angiopoietin-5; ANGPTL3;   FHBL2

Assay Procedure

Refer to the product datasheet for the complete assay procedure.

Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.

1Prepare all reagents, standard dilutions, and samples as directed in the product insert.

2Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

3Add 50 μL of Assay Diluent to each well.

4Add 50 μL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours.

5Aspirate each well and wash, repeating the process 4 times for a total of 5 washes.

6Add 100 μL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours.

7Aspirate and wash 5 times.

8Add 100 μL Substrate Solution to each well.

9Add 100 μL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
