Analysis of F13B Gene (Mutation) by RT-qPCR (CAT#: STEM-MT-0173-LGZ)

Introduction

Also known as: FXIIIB
This gene encodes the coagulation factor XIII B subunit. Coagulation factor XIII is the last activated zymogen in the coagulation cascade. Plasma factor XIII is a heterotetramer composed of 2 a subunits and 2 b subunits. Among them, the A subunit has a catalytic effect, and the B subunit has no enzymatic activity, and can be used as a plasma carrier molecule. Platelet factor XIII consists of only 2 A subunits and is of the same origin as plasma. When thrombin cleaves the activating peptide and is activated in the presence of calcium ions, plasma factor XIII dissociates its B subunit and produces factor XIIIa, the same active enzyme as platelet factor XIII. This enzyme acts as a transglutaminase, catalyzing the formation of γ-glutamine-ε-lysine crosslinks between fibrin molecules, thereby stabilizing the fibrin clot. Factor thirteen deficiency falls into two categories: type I deficiency, which is characterized by the absence of both the A and B subunits, and type II deficiency, which is characterized by the absence of the A subunit. These defects can lead to lifelong bleeding tendencies, defective wound healing, and recurrent miscarriages.




Principle

Quantitative reverse transcription PCR (RT-qPCR) is an experimental method applied to PCR experiments using RNA as the starting material. In this method, total or messenger RNA (mRNA) is first transcribed into complementary DNA (cDNA) by reverse transcriptase. Subsequently, qPCR reaction was performed using cDNA as template.

Applications

Factor XIII, b subunit, deficiency of, Hereditary factor XIII deficiency disease

Procedure

1. Sample processing and preparation of PCR reaction system.
2. Add the amplification template, cover the PCR reaction cover, mix well, centrifuge at low speed instantaneously, and transfer to the PCR instrument.
3. Set the program for PCR amplification.
4. Data analysis.
