Overview
Host Type: Rabbit
Antibody Clonality: Polyclonal
Regulatory Status: RUO
Target Species: Human
Application: Immunoprecipitation (IP)
Storage:
The lyophilized antiserum is shipped at ambient temperature and may be stored at +4°C; prolonged storage at or below -20°C. Dilutions may be prepared by adding phosphate buffered saline (PBS pH 7.2). Repeated thawing and freezing should be avoided. If a slight precipitation occurs upon storage this should be removed by centrifugation. It will not affect the performance of the antiserum. Diluted antiserum should be stored at +4°C not refrozen and preferably used the same day.
Further Information
Applications Description:
Precipitation assays. In immunoelectrophoresis in agarose-plates use 2 ul human plasma or equivalent against 120 ul antiserum. In double radial immunodiffusion use a rosette arrangement with 10 ul antiserum in 3 mm diameter center well and 2 ul plasma samples (neat and serially diluted) in 2 mm diameter peripheral wells. In electroimmunodiffusion the amount of antiserum required in the agarose gel is usually between 1 and 2% depending on the test arrangement.
Background:
The defined antibody reactivity is restricted to Factor XIII and FXIIIa in plasma and to platelet FXIII. As tested at the level of sensitivity of immunoprecipitation techniques a single precipitin line is obtained in bidimensional electrophoresis, immunoelectrophoresis and double radial immunodiffusion (Ouchterlony) which shows a reaction of full identity with A subunits of FXIII. No reaction is obtained with FXIII-depleted plasma and with B subunits. In precipitating techniques as electroimmunodiffusion, immunoelectrophoresis and single and double radial immunodiffusion (Mancini, Ouchterlony). To prepare an adsorbent for immunoaffinity purification of FXIII. If used in more sensitive test procedures or as catching or detection antibody in solid phase immunoassays specificity controls should always be include. Increase in plasma FXIII has been observed in type IV hyperlipoproteinaemia and in combined hyperlipodaemia. Congenital and acquired FXIII deficiencies have also been reported. In some cases of myeloma, inhibition of FXIII activity by the paraproteins may occur.

Product:
Delipidated, heat inactivated, lyophilized, stable whole serum. No preservative added. Total protein and IgG concentrations in the antiserum are comparable to those of pooled normal rabbit serum. No foreign proteins added. Reconstitute the lyophilized antiserum by adding 1 ml sterile distilled water.
Source:
Plasma FXIII is an active transglutaminase until it is activated (FXIIIa). It consists of two A subunits joined as a dimer, connected to two B subunits (A2B2). Each A subunit has a molecular weight of 75,000 and each B subunit of 80,000, making an aggregate molecular weight of the whole molecule of 320,000. Normal plasma contains about 20mg/ml. Platelet FXIII consists of only A subunits synthesized in the megakaryocytes. It accounts for about 50% of the total blood FXIII activity with a linear relationship between FXIII level and platelet counts. RAHu/FXIII-A reacts with both plasma and platelet FXIII. Antiserum raised against the B subunit (RAHu/FXIII-S) reacts exclusively with native and activated FXIIIa in plasma. FXIIIa results from activation of FXIII by thrombin after the release of fibrinopeptides A from fibrinogen. Highly purified FXIII-A is used for the immunization. Freund?s complete adjuvant is used in the first step of the immunization procedure.
