For Research Use Only. Not for use in diagnostic procedures.

This assay has high sensitivity and excellent specificity for detection of Coagulation Factor XIII B Polypeptide (F13B).
No significant cross-reactivity or interference between Coagulation Factor XIII B Polypeptide (F13B) and analogues was observed.

The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Manufactured in an ISO 9001:2008 and ISO 13485:2003 Certified Laboratory.

Manufactured in a lab with traceable raw materials. Bulk orders can typically be prepared to the customera??s specifications, please inquire.

Select online data sheet information is drawn from bioinformatics databases, occasionally resulting in ambiguous or non-relevant product information. It is the responsibility of the customer to review, verify, and evaluate the information to make sure it matches their requirements before purchasing the kit. Our ELISA Kit assays are dynamic research tools and sometimes they may be updated and improved. If the format of this assay is important to you then please request the current manual or contact our technical support team with a presales inquiry before placing an order. We will confirm the current details of the assay. We cannot guarantee the sample manual posted online is the most current manual.

Small volumes of F13B elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS2024954 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Coagulation Factor XIII B Polypeptide (F13B) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing F13B. The ELISA analytical biochemical technique of the MBS2024954 kit is based on F13B antibody-F13B antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect F13B antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, F13B. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Coagulation Factor XIII B Polypeptide (F13B) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Coagulation Factor XIII B Polypeptide (F13B) and unlabeled Coagulation Factor XIII B Polypeptide (F13B) (Standards or samples) with the pre-coated antibody specific to Coagulation Factor XIII B Polypeptide (F13B). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Coagulation Factor XIII B Polypeptide (F13B) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Coagulation Factor XIII B Polypeptide (F13B) in the sample.

F13B_HUMAN

This gene encodes coagulation factor XIII B subunit. Coagulation factor XIII is the last zymogen to become activated in the blood coagulation cascade. Plasma factor XIII is a heterotetramer composed of 2 A subunits and 2 B subunits. The A subunits have catalytic function, and the B subunits do not have enzymatic activity and may serve as a plasma carrier molecules. Platelet factor XIII is comprised only of 2 A subunits, which are identical to those of plasma origin. Upon activation by the cleavage of the activation peptide by thrombin and in the presence of calcium ion, the plasma factor XIII dissociates its B subunits and yields the same active enzyme, factor XIIIa, as platelet factor XIII. This enzyme acts as a transglutaminase to catalyze the formation of gamma-glutamyl-epsilon-lysine crosslinking between fibrin molecules, thus stabilizing the fibrin clot. Factor XIII deficiency is classified into two categories: type I deficiency, characterized by the lack of both the A and B subunits; and type II deficiency, characterized by the lack of the A subunit alone. These defects can result in a lifelong bleeding tendency, defective wound healing, and habitual abortion. [provided by RefSeq, Jul 2008]

F13B: The B chain of factor XIII is not catalytically active, but is thought to stabilize the A subunits and regulate the rate of transglutaminase formation by thrombin. Defects in F13B are the cause of factor XIII subunit B deficiency (FA13BD). FA13BD is an autosomal recessive disorder characterized by a life-long bleeding tendency, impaired wound healing and spontaneous abortion in affected women.
