Price: 320 € / 1 ml

Monoclonal Antibodies

Origin:	Mouse

Isotype:	IgG1

Clone:	O10

Format:	liquid conc.

Quantity:	1 ml

Concentration:	50 µg/ml

Working concentration:	1-4 µg/ml

Presentation:	Protein G affinity purified IgG in PBS pH 7.3 with BSA and sodium azide (0.09%)

Immunogen:	Human thymocytes

Specificity:	Human CD1a, possible cross-reactivity with CD1b

Species Specificity:	Human

General Information:	Up to now CD1 has been identified as five different variants encoded by 5 different genes (they are designed as CD1a, b, c, d and e). CD1 is exprimed by cortical thymocytes, Langerhans cells in epithelia and dendric cells. Usually it doesn't occur in mature peripheral blood cells, but is exprimed intra-cytoplasmatically in activated T-cells. CD1a plays a role in the detection of graft versus host reaction, in the detection of interdigitating cells in artereosclerotic lesion and in asthmatic inflammation.

Special properties:	Clone O10 is well suited for labelling of CD1a in different tissues. It is used for the detection of Langerhans-Cells and dendritic cells in the skin and other tissues.

Positive control:	Skin, tonsil

Pre-treatment:	Pre-treatment of formaldehyde-fixed material should be treated with Unmasking Solution E, TRIS-buffered EDTA pH 9 (Art. No. DE006) at 96-100°C

Applications:	IHC(P)

Incubation time:	60 min at RT

Secondary reagents:	We recommend the use of BIOLOGO's Universal Staining System DAB (Art. No. DA005) or AEC (Art. No. AE005), for higher sensitivities VECTASTAIN Elite ABC (Art. No. PK-6101) or ABC AP (Art. No. AK-5001) systems are applicable.

Storage:	2-8°C
